Question

Speed of electromagnetic waves is

Answer 1

All waves of electromagnetic radiation travel at the speed of 3 x 108 m/s (in a vacuum). When traveling in other media, such as air or water, the speed of electromagnetic waves is only slightly slower. f) Find the wavelength of a wave of electromagnetic radiation that has a frequency of 6 x 1014 Hz.

Answer 2

Electromagnetic waves are created by the vibration of an electric charge. This vibration creates a wave which has both an electric and a magnetic component. An electromagnetic wave transports its energy through a vacuum at a speed of 3.00 x 108 m/s (a speed value commonly represented by the symbol c).
