## Top best answers to the question «Do electromagnetic waves require a wave»

• These changing fields form electromagnetic waves. Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate . This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

FAQ

Those who are looking for an answer to the question «Do electromagnetic waves require a wave?» often ask the following questions:

### 👋 Electromagnetic waves are ___ wave?

EM waves are 'transverse' waves. This means that they are measured by their amplitude (height) and wavelength (distance between the highest/lowest points of two consecutive waves).

### 👋 Do electromagnetic waves require a medium to propagate?

• No, electromagnetic waves do not require any medium to propagate. No, mechanical waves do not require any medium to propagate. Yes, both mechanical and electromagnetic waves require a medium to propagate. Yes, all transverse waves require a medium to travel.

### 👋 What are long-wave electromagnetic waves?

• (See this figure .) These extremely long wavelength electromagnetic waves (about 6000 km!) are one means of energy loss in long-distance power transmission. This high-voltage traction power line running to Eutingen Railway Substation in Germany radiates electromagnetic waves with very long wavelengths. (credit: Zonk43, Wikimedia Commons)

We've handpicked 23 related questions for you, similar to «Do electromagnetic waves require a wave?» so you can surely find the answer!

What are electromagnetic waves?
• Electromagnetic waves are waves of energy that, in vacuum, move at the speed of light. Because of this, these waves can be used for a variety of purposes and have wide ranging practical applications
What causes electromagnetic waves?
• Electromagnetic waves are caused by electronic devices nearby. Tiny electrical currents exist in the human body which can react with the electromagnetic waves. For example, nerves transmit electric impulses to the brain which can later be affected by the electromagnetic wave and have a positive charge.
What generates electromagnetic waves?
• Electromagnetic waves are generated by moving electrons. An electron generates an electric field which we can visualize as lines radiating from the electron Figure 10a.
What is electromagnetic waves?

Electromagnetic waves are transverse (unpolarized or polarized) or circularly polarized waves that have some electrical properties and some magnetic properties. An electromagnetic wave consists of changing electric and magnetic fields. The repeated cyclic transfer of energy from the electric field (weakening it) to the magnetic field (strengthening it) until the electric field is gone, then from the magnetic field (weakening it) to the electric field (strengthening it) until the magnetic field is gone every cycle is the process by which electromagnetic waves propagate without requiring a medium (and is described in Maxwell's Equations).

What produces electromagnetic waves?
• Electromagnetic waves are produced by the motion of electrically charged particles. These waves are also called "electromagnetic radiation" because they radiate from the electrically charged particles. They travel through empty space as well as through air and other substances.
Are electromagnetic waves slower than sound waves?

Sound waves travel slower than electromagnetic waves since sound waves are compressional waves where they compress and decompress the medium and its...

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.

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.

What type of waves are electromagnetic 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.
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.
Electromagnetic waves are described as what type of wave?

EM waves are 'transverse' waves. This means that they are measured by their amplitude (height) and wavelength (distance between the highest/lowest points of two consecutive waves).

How much faster are electromagnetic waves than sound wave?
• While sound waves only act as waves, EM waves act as waves as well as particles. Another major difference is EM waves travel at the speed of light, which is much faster than the speed of sound.
What are electromagnetic waves have the shortest wave lengths?
• Ultraviolet waves have even shorter wavelengths than visible light. UV waves are the cause of sunburn and can cause cancer in living organisms. High-temperature processes emit UV rays; these can be detected throughout the universe from every star in the sky.
What can electromagnetic waves do that mechanical wave cannot?

Electromagnetic waves can travel through a vacuum.

What wave has the highest frequency of electromagnetic waves?

To ... flowchart: cosmic ray->gamma->X-ray->UV->light->IR->radio wave/// Radio wave can be divided in many categories w.r.t. fequencies.... regards Raktim

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.

Are the electromagnetic waves transverse?
• What are the Characteristics of Electromagnetic Waves? Electromagnetic waves are transverse in nature as they propagate by varying the electric and magnetic fields such that the two fields are perpendicular to each other. Accelerated charges are responsible to produce electromagnetic waves. Electromagnetic waves have constant velocity in vacuum and it is nearly equal to which is denoted by = . More items...
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.

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.

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 electromagnetic waves move themselves?
• Likewise, the electric and the magnetic field do not move themselves. But every point of a field changes its state, and those changes propagate. That said, the depiction of a EM wave as wobbly rope is inherently wrong. The wobbly rope image is not a depiction of a radio wave itself.
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 classified?
