Electromagnetic Radiation travels through vacuum at a speed of ______m/s

The speed of light (electromagnetic radiation) through vacuum has a constant value of 3.00 x 108m/s and is independent of the wavelength in vacuum.

Electromagnetic radiation

Electromagnetic radiation is a type of energy that is commonly known as light. ; All electromagnetic radiation travels at the same speed, which is about 3.0 × 108 meters per second, through a vacuum. The speed of electromagnetic waves in a vacuum depends upon the source of radiation. As we go from gamma rays to radio waves, the frequency decreases, and wavelength increases, thereby maintaining the product constantly.
