How do you know that electromagnetic wave are not compression wave?

If they were they would not travel through a vacuum because there would be nothing to compress. But they do travel through vacuums, so they can't be compression waves.

The above does not exclude a medium that can exist in a vacuum
For EM waves to be a compression wave, it must have some medium.
For many years, the ether/aether was considered to be the medium, but the Michelson-Morley experiment failed to show any effect consistent with ether/aether, and the concept is now considered invalied.
So, since the ether/aether cannot be detected, EM waves have no medium, so EM waves are not compression waves.

Are compression waves in an electromagnetic spectrum?
1. A compression wave is when the particles in a wave are close together and not spread out. 2. A compression wave is where the pressure in the waves is higher than atmospheric pressure in that particular area where the particles come together.
Is the light wave electromagnetic or no?
The light wave is electromagnetic yes.
What kind of Wave is an electromagnetic wave how fast does it travel?
An electromagnetic wave is a wave with electric component and magnetic component. In free space (vacuum), an electromagnetic wave travels with the speed of light, that is 3x10^8 m/s. In fact, light is also an electromagnetic wave.
Energy that travels at speed of light?
That can be light, or some other electromagnetic wave (light is an electromagnetic wave), or gravitational waves.
Is a radio wave mechanical or electromagnetic wave?
Radio waves are electromagnetic. That's how they can get down here from satellites.
What is the difference between compression wave and electromagnetic wave?
You mean longitudinal wave by compression wave? Electromagnetic wave is transverse in nature. It does not need a material medium. It can pass even through vacuum. But compression waves bady needs a material medium.
What part of the electromagnetic spectrum does the ultrasonic wave falls into?
An ultrasonic wave is not an electromagnetic wave; it is a sound wave.An ultrasonic wave is not an electromagnetic wave; it is a sound wave.An ultrasonic wave is not an electromagnetic wave; it is a sound wave.An ultrasonic wave is not an electromagnetic wave; it is a sound wave.
Tell how you know if a wave is electromagnetic in character?
A wave is electromagnetic in character if the wave is produced by the acceleration of an electric charge. Another indication is a wave is electromagnetic if it is propagated by the periodic variation of intensities of, usually, perpendicular electric and magnetic fields.
Which wave is not electromagnetic wave?
Mexican Wave? A non-electromagnetic wave.
How to calculate the frequency of an electromagnetic wave you need to know the speed of the wave and its?
You need to know it speed, wavelenght and its frequency.
What makes a compression wave?
compression wave is a wave like a sound wave
What type of wave is a light wave an example of?
Light is an example of a electromagnetic wave.
If you know the wavelength of an electromagnetic wave in a vacuum you can calculate its?
Momentum, energy, frequency, and wave number (but not wave vector.)
What type of wave requires a material medium through which to travel?
We know that mechanical waves require a medium through which to travel. An example of a mechanical wave is a sound (acoustic) wave. The wave transfers its energy into the medium so that it can propagate through it. In contrast, electromagnetic waves don't require a medium through which to travel. They move perfectly well through the vacuum of space.
Are compression waves in an electromagnetic spectrum?
1. A compression wave is when the particles in a wave are close together and not spread out. 2. A compression wave is where the pressure in the waves is higher than atmospheric pressure in that particular area where the particles come together.
What kind of wave does electromagnetic energy travel in?
The wave is called an electromagnetic wave.
Is light a mechanial wave or an electromagnetic wave A tranverse wave or a compressional wave?
electromagnetic, transverse
