For electromagnetic radiation the speed of light equals?
Light is electromagnetic radiation. The speed of light in a vacuum is the speed for all electromagnetic radiation, as long as it is measured in vacuo.When e-m radiation travels through something other than a vacuum, it travels more slowly. How much slower sometimes varies according to the wavelength of the radiation.
What is speed does light travel?
