Light in a vacuum is represented by a constant known as c=2.99792458 m/s. Otherwise I can recommend two books called general relativity and special relativity both written by our very own Albert Einstein.

Radio waves, microwaves, infrared, visible light, ultra violet, XRays, and gamma rays are all part of the "electromagnetic spectrum". They are all electromagnetic radiation and they all travel at the speed of light. The only difference between them is their frequencies (or wavelengths.

The speed of light is a constant, often called c ... however, scientists have found that that constant is, as I said, through a vacuum. Light travels slower, for example, through water.

How do electromagnetic waves travel through a medium?
electromagnetic waves generally don't require a medium to travel. the most commonly visible example is "light" which may be either sun's light, light from a bulb or any other source. they travel as transverse waves.
What type of waves is produced during an earthquake?
Seismic waves consist ofP waves which travel through the Earth fast. They compress the medium they travel through;S waves which also travel through the Earth, shearing the solid Earth as they go. S waves do not travel through liquid;Surface waves which can cause the Earth to undulate like water waves or surface waves that cause the Earth to shear.
Does waves need a medium to travel through?
No. Electromagnetic waves travel through vacuum ( ie space where there is nothing)
Is it true that different kinds of E-M waves travel through space at different speeds?
No. All E-M waves travel through space at the same speed, known as the"Speed of Light".
What type of wave can travel to space?
im pretty sure shock waves do. and light wave def. do.
How do sound waves travel compared to light waves?
light waves fast
Why is diffraction of sound waves more easily observed than diffraction of light waves?
sound waves travel fast than light waves
What are similarities of light and sound?
They both travel in the form of waves, and they both travel very fast.
How fast does theRadio waves travel?
Radio waves travel at the speed of light 300 Million meters/second, 300e6 meters/second
How fast does light waves travel per second?
186,282.4 miles per second.
Speed of electromagnetic waves?
They travel at the same speed of light that is 299,792,458 msec-1
How fast is electronic dynamic waves travel to the space.?
I assume you mean electromagnetic waves. In outer space, they will travel at the speed of light (since light is also an electrodynamic wave). This speed is about 300,000 kilometers per second.
How fast do light waves travel in space?
Since space is a vacuum, light travels at approximately 300,000,000 metres per second.
Do sound waves or light waves travel faster?
In air, light waves travel about 871 thousand times faster than sound waves.
How fast do electromagnetic waves travel in vacuum?
At the speed of light which is approx 3 x 108 meters/second
How does light travel through AVACUUM?
Light waves do not need a medium to propagate. Sound waves cannot travel without a medium. Light waves always travel at the speed of light that is 3*108m/s.
Which can travel as fast as the speed of light?
-- radio waves-- microwaves-- heart waves-- infrared waves-- all of the visible colors-- ultraviolet waves-- X-rays-- gamma rays
