All electromagnetic waves travel at the same speed in a vacuum, usually referred to as the speed of light. This speed is approximately 300,000 kilometers per second and is represented by the symbol c. Identify the formula you can use to calculate the speed of an electromagnetic wave.

The following formula is used to calculate the speed or velocity of a wave. V = f * w Where V is the velocity (m/s) f is the frequency (hz)

the answer is 303.15 or 303
