Radio waves travel at the speed of light. Marsha listen to radio station at 91.3 mHz, which is a frequency of 9.13*10^ 7 H2 What is the wavelength of this radio signal in a vacuum?

3.29 meters

Explanation:

c = λ f

c = speed of light = 3 * 10^8 m/s

λ = wavelength

f = frequency

3 * 10^8 m/s = λ * (9.13 * 10^7 1/s)

λ  = (3 * 10^8 m/s) / (9.13 * 10^7 1/s)

λ  = 3.29 m
