Question

The speed of all electromagnetic waves through space is 300,000,000 m/s. What is the frequency of a radio wave that has a wavelength of 10m?

Answer 1

A radio wave with a wavelength of 10 meters and has a frequency of (300,000,000 / 10) = 30 MHz.

300,000,000 meters = 186,282 miles

A radio wave with a wavelength of 10 miles has a frequency of (186,282 / 10) =

18,628 Hz.
