Question

A particular radio station broadcast radio waves at 100 MHz (100 million Hz). If the radio waves travel at the speed of light (300 million m/s), then what is the wavelength of the radio waves that the station is broadcasting?

Answer 1

Wavelength  =  (speed) / (frequency)

                      =  (3 x 10⁸ m/s) / (1 x 10⁸ /s)  =  3 meters
