Those interested in the Amplitude electromagnetic waves formula category often ask the following questions:

### ☑️ What is the formula for electromagnetic waves?

• So our formula for EM waves (in vacuum) is: c=f⋅λ;c=3⋅108m s. The continuum of various wavelengths and frequencies for EM waves is called the Electromagnetic Spectrum. It turns out that the speed of light is also the ratio of the strengths of the Electric and Magnetic fields in an EM wave.

### ☑️ Do all electromagnetic waves have the same amplitude?

No, radiation with a high amplitude always has a higher energy density than radiation with a low amplitude… Example: Microwave frequency = 3 Ghz, X ray frequency = 3 EHz, S = 1 W/m2 in both cases, consequently the amplitude of E is identical for both frequencies, and so is the amplitude of H.

### ☑️ What is the formula to find amplitude and speed of waves?

-- Speed of a wave = (frequency) times (wavelength) -- There is no general formula for amplitude.

### ☑️ How are the amplitude and intensity of electromagnetic waves related?

• This is true for waves on guitar strings, for water waves, and for sound waves, where amplitude is proportional to pressure. In electromagnetic waves, the amplitude is the maximum field strength of the electric and magnetic fields. (See Figure 1.) Thus the energy carried and the intensity I...

### ☑️ Are light waves electromagnetic waves?

Usually when one says light waves, one is referring to Visible light. Any light wave, and hence visible light, is an electromagnetic wave. As an electromagnetic wave, it is also a transverse wave. The oscillating electric and magnetic fields of an electromagnetic wave in free space are oscillating with a direction perpendicular yo the direction of movement of the wave. The velocity of an electromagnetic wave is the sped of light. This is a sensible things since light is an electromagnetic wave. In a vacuum all electromagnetic waves travel at the same speed. In matter, if the matter allows an electromagnetic wave to propagate, the speed is slower than the speed of light and in optics we say the speed is reduce by the index of refraction, v=c/n. Electromagnetic waves, like all waves, have velocity, wavelength, frequency, amplitude and phase. As with all transverse waves, electromagnetic waves can be polarized, or we say, have a polarization. Electromagnetic waves have electric and magnetic fields that are sinusoidal in space and time. These electromagnetic fields satisfy Maxwell's equations, i.e. the fundamental laws of electromagnetism. There is a quantum version of electromagnetic theory called electrodynamics and that theory is the necessary edification of Maxwell's equations to describe the quantum nature of light. Thus, even when we are discussing light as photons, it is correct to say light is an electromagnetic wave as such is manifested within quantum electrodynamics.

### Do light waves have amplitude?

Light is an electromagnetic wave, so it has an amplitude measured in volts per meter in one direction perpendicular to its propagation direction, and an amplitude measured in tesla in the remaining perpendicular direction.

### What are high amplitude waves?

• A high amplitude wave is a high-energy wave, and a low-amplitude wave is a low-energy wave. In the case of sound waves, a high amplitude sound will be loud, and a low amplitude sound will be quiet. Or with light waves, a high amplitude beam of light will be bright, and a low amplitude beam of light will be dim.

### What kind of waves are electromagnetic waves?

Radio waves, television waves, and microwaves are all types of electromagnetic waves. They only differ from each other in wavelength. Wavelength is the distance between one wave crest to the next.

### Are electromagnetic waves classified as longitudinal waves?

No. Electromagnetic waves are classified as transverse waves because the electric and magnetic fields are perpendicular to the direction of propagation.

### What distinguished electromagnetic waves from mechanical waves?

In a mechanical wave, some material is between stretched or moved from its ground, or normal, state. In an EM wave, a changing electrical field creates a changing magnetic field, which creates a changing E-field; and the process continues until these fields meet something that absorbs them. There is not material that is stretched or moved, the fields just operate on their own. EM waves operate quite well in the absence of any material whatsoever; mechanical waves need some media to propogate in.

### Are electromagnetic waves transverse or longitudinal waves?

Electromagnetic waves are transverse waves. That means the electric and magnetic fields change (oscillate) in a plane that is perpendicular to the direction of propagation of the wave. Also note that electric and magnetic fields in an EM wave are also perpendicular to each other.

### Does electromagnetic waves consist of infrared waves?

If you mean are infrared waves electromagnetic radiation, then yes. Infrared is a wavelength of electromagnetic radiation. It has a wavelength between 750 nanometers and 1 millimeter.

### Electromagnetic waves are classified as longitudinal waves?

No. Sound waves are longitudinal. This means that the motion of the wave is back and forth in the same direction in which the wave is moving. With electromagnetic waves, electric force fields and magnetic force fields form mutually perpendicular sine waves, both perpendicular to the direction in which the wave propagates. Hence electromagnetic waves are transverse waves, not longitudinal.

### Are electromagnetic waves slower than sound waves?

### Are radio waves and light waves both electromagnetic waves?

• Both radio waves and light are electromagnetic waves; their main difference is their frequency. Radio waves are created by the acceleration of electrons in a radio antenna, and light waves are created by the oscillations of the electrons within atoms.

### How are electromagnetic spectrum and electromagnetic waves related?

electromagnetic waves are from the spectrum

### What is the formula for amplitude of a wave?

To find the amplitude, wavelength, period, and frequency of a sinusoidal wave, write down the wave function in the form y(x,t)=Asin(kx−ωt+ϕ). The amplitude can be read straight from the equation and is equal to A. The period of the wave can be derived from the angular frequency (T=2πω).

### How do electromagnetic waves move?

• Electromagnetic waves are formed by the vibrations of electric and magnetic fields. These fields are perpendicular to one another in the direction the wave is traveling. Once formed, this energy travels at the speed of light until further interaction with matter.

### How dangerous are electromagnetic waves?

• Electromagnetic wave is dangerous, electromagnetic radiation makes us leukemia, cancer, and cataract. Such rumors about electromagnetic radiation’s risk are in many websites and books. Electromagnetic wave and electromagnetic radiation are invisible, odorless, and of course, vapidly.

### What oscillates in electromagnetic waves?

The radiation has both an electric component and a magnetic one, both as waves, where the electric field is perpendicular to the magnetic field, and synchronised. Both fields oscillate, i.e. the amplitude changes cyclically, in its simplest form as a sine wave.

### What causes electromagnetic waves science?

EM radiation is created when an atomic particle, such as an electron, is accelerated by an electric field, causing it to move. The movement produces oscillating electric and magnetic fields, which travel at right angles to each other in a bundle of light energy called a photon.

### How are electromagnetic waves transfered?

Electromagnetic waves are transferred by electromagnetic radiation.

### Why electromagnetic waves are transverse?

Electromagnetic waves are also transverse waves because the direction of particle displacement is also perpendicular to the direction of movement, producing the waveform of visible light, and other types of electromagnetic radiation.

### Do electromagnetic waves carry particles?

Charged particles—such as electrons and protons—create electromagnetic fields when they move, and these fields transport the type of energy we call electromagnetic radiation, or light.

### Which electromagnetic waves travel fastest?

Any of them, in a vacuum. They all travel at the speed of light.

### Electromagnetic waves are made of?

Electromagnetic waves carries by the small particles named "Photon".

### Do electromagnetic waves have longitudinal?

Although both wave types are sinusoidal, transverse waves oscillate perpendicular to the direction of propagation, while longitudinal waves oscillate parallel to the direction of propagation… All electromagnetic waves (light waves, microwaves, X-rays, radio waves) are transverse. All sound waves are longitudinal.

### What electromagnetic waves cannot transfer?

There is no sound in space because there are no molecules there to transmit the sound waves. Electromagnetic waves are not like sound waves because they do not need molecules to travel. This means that electromagnetic waves can travel through air, solid objects and even space.

### Do electromagnetic waves move parallel?

Electromagnetic waves are transverse waves… Linearly polarized waves If the electric field (and hence the magnetic field) changes in such a way that its direction remains parallel to a line in space as the wave travels, the wave is called linearly polarized.

### Do humans produce electromagnetic waves?

Yes, all objects, including human bodies, emit electromagnetic radiation. The wavelength of radiation emitted depends on the temperature of the objects. Such radiation is sometimes called thermal radiation. Most of the radiation emitted by human body is in the infrared region, mainly at the wavelength of 12 micron.

### How are electromagnetic waves generated?

An electromagnetic wave can be created by accelerating charges; moving charges back and forth will produce oscillating electric and magnetic fields, and these travel at the speed of light.

### Are all transverse waves electromagnetic?

no,not at all,we can create a transverse wave in water ,like sea waves which are sinusoidal in nature

### Does photons produces electromagnetic waves?

Not exactly. Actually, no. Photons are chunks of electromagnetic waves. As such, they do not produce EM waves, they ARE those waves. A photon inter-acting with some other particle could result in other photons -- ie, a different kind of EM wave -- being created.

### What can disrupt electromagnetic waves?

Thin amounts of plastic wrap, wax paper, cotton and rubber are not likely to interfere with radio waves. However, aluminum foil, and other electrically conductive metals such as copper, can reflect and absorb the radio waves and consequently interferes with their transmission.

### Are electromagnetic waves the fastest?

Electromagnetic waves in a vacuum are faster than in any other medium. In a vacuum, all electromagnetic waves propagate at the same speed. In other media, the speed varies with the frequency. For example, visible light of longer wavelengths is generally faster in glass than shorter wavelengths.

### How are electromagnetic waves classified?

By there wavelength and frequency

### How are electromagnetic waves different from mechanical waves?

• Magnetism can also be static, as it is in a refrigerator magnet. A changing magnetic field will induce a changing electric field and vice-versa—the two are linked. These changing fields form electromagnetic waves. Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate.

### How are sound waves converted to electromagnetic waves?

• EM waves don’t need a medium in which to propagate; they can travel through a vacuum, such as outer space. A radio works because sound waves played by the D.J. at the radio station are converted into electromagnetic waves, then encoded and transmitted in the radio-frequency range.

### When do electromagnetic waves behave as plane waves?

• The electromagnetic waves generating from sources are spherical. At large distances from the sources, they behave as plane waves. When the electric (E) and magnetic (H) field vectors of a wave are in planes perpendicular to the direction of propagation, say the z-direction, it is called a plane wave.
