Top best answers to the question «What does electromagnetic wave mean»
- Description: Electromagnetic waves are formed when an electric field comes in contact with a magnetic field. They are hence known as ‘electromagnetic’ waves. The electric field and magnetic field of an electromagnetic wave are perpendicular (at right angles) to each other.

An electromagnetic wave, in its simplest description, is a wave that as it propagates keeps converting its magnetic field into an electric field while converting its electric field into a magnetic field.
We've handpicked 27 related questions for you, similar to «What does electromagnetic wave mean?» so you can surely find the answer!
What does an electromagnetic wave do to technology?- First, an electromagnetic wave hits the atoms of a physical material, which absorbs the wave. Vibrations. The absorption of this electromagnetic energy causes the electrons within this atom to start vibrating. Release.
- An electromagnetic wave such as light consists of a coupled oscillating electric field and magnetic field which are always perpendicular to each other; by convention, the "polarization" of electromagnetic waves refers to the direction of the electric field. In linear polarization, the fields oscillate in a single direction.
- transverse-electromagnetic (TEM) wave because the electric and magnetic field components are oriented in the transverse direction relative to the direction of wave propagation. This form of EM wave is one of the most common ones when working with lasers.
What kind of electromagnetic waves does a light bulb use?
- What kind of electromagnetic waves does a light bulbs use? It doesn't ' USE ' any; that is, you don't have to provide any electromagnetic waves in order for a light bulb to do its job. In the course of doing its job, the light bulb PRODUCES light and heat waves. A fluorescent light also produces radio waves.

Does electromagnetic wave energy affect earth?
Almost all of the energy available at Earth's surface comes from the sun… This energy eventually makes its way to the outer regions of the sun and is radiated or emitted away in the form of energy, known as electromagnetic radiation.
How does an electromagnetic wave produce?Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields.

How does an electromagnetic wave start?
- How Electromagnetic Waves Begin. An electromagnetic wave begins when an electrically charged particle vibrates. When a charged particle vibrates, it causes the electric field surrounding it to vibrate as well. A vibrating electric field, in turn, creates a vibrating magnetic field.
- According to quantum mechanics, electromagnetic waves can also be viewed as streams of particles called photons. When viewed in this way, the polarization of an electromagnetic wave is determined by a quantum mechanical property of photons called their spin.
How does an electromagnetic wave begin? how does it travel?
- An electromagnetic wave begins when an electrically charged particle vibrates. This causes a vibrating electric field, which in turn creates a vibrating magnetic field. The two vibrating fields together form an electromagnetic wave. Beside above, can electromagnetic waves travel through matter?

What creates an electromagnetic wave?
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.
An electromagnetic wave is a stream of photons which behaves both like waves and particles. They move perpendicular to the direction of propagation. They have 2 mutually perpendicular components of electric and magnetic fields.
Visible light is that part of the electromagnetic spectrum that is seen as colours: violet, indigo, blue, green, yellow, orange and red. Blue light has a very short wavelength, and so produces a higher amount of energy.
What electromagnetic wave is harmful?There are two main categories of EMFs: Higher-frequency EMFs, which include x-rays and gamma rays. These EMFs are in the ionizing radiation part of the electromagnetic spectrum and can damage DNA or cells directly.
What electromagnetic wave is longest?- Nearly all frequencies and wavelengths of electromagnetic radiation can be used for spectroscopy. Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.
Photons travel in harmonic waves at the fastest speed possible in the universe: 186,282 miles per second (299,792,458 meters per second) in a vacuum, also known as the speed of light. The waves have certain characteristics, given as frequency, wavelength or energy.
What is electromagnetic wave equation?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.
- Description: Electromagnetic waves are formed when an electric field comes in contact with a magnetic field. They are hence known as ‘electromagnetic’ waves. The electric field and magnetic field of an electromagnetic wave are perpendicular (at right angles) to each other. They are also perpendicular to the direction of the EM wave.

What makes up electromagnetic wave?
Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields… They are also perpendicular to the direction of the EM wave.
What properties describe electromagnetic wave?Like other waves, electromagnetic waves have properties of speed, wavelength, and frequency.
What does alpha wave mean?- Alpha wave. Alpha waves are neural oscillations in the frequency range of 8–12 Hz arising from the synchronous and coherent (in phase or constructive) electrical activity of thalamic pacemaker cells in humans. They are also called Berger 's waves after the founder of EEG .
- A blast wave is an area of pressure that expands outward from a central explosive point. It is comprised of a highly concentrated high-pressure front (the blast front) and travels at supersonic speeds.
