Radio waves travel at the speed of light, 3.0 * 108 m/s. What is the wavelength of a radio wave from an AM station broadcasting at a frequency of 7.5 * 105 Hz? (λ = v / f)

4 * 10^2 M

Step-by-step explanation:

We are given;

Speed of light as 3.0 * 10^8 m/s

Frequency of radio wave as 7.5 * 10^5 Hz

We are required to determine the wavelength.

Using the formula;

wavelength, λ = v/f

Note; Radio wave is an electromagnetic wave, therefore travels with the speed of light.

Therefore;

wavelength, λ = 3.0 * 10^8 m/s : 7.5 * 10^5 Hz

= 4 * 10^2 M

Hence, the wavelength of the radio wave is 4 * 10^2 M
