Question

Consider your favorite radio station. AM radio has a frequency between 535 kilohertz and 1605 kilohertz, and FM radio has a frequency between 88 megahertz and 108 megahertz. Calculate the wavelength and the energy of the electromagnetic waves from your favorite radio station.

Answer 1

The wavelength for 550 kHz signal is

`\lambda = (3.00 * 10^8)/(550* 10^3)`

λ = 545.45 m

The wavelength for 1600 kHz signal is

`\lambda = (3.00 * 10^8)/(1600* 10^3)`

λ = 187.5 m

The wavelength for 88 MHz signal is

`\lambda = (3.00 * 10^8)/(88* 10^6)`

λ = 3.41 m

The wavelength for 108 MHz signal is

`\lambda = (3.00 * 10^8)/(108* 10^6)`

λ = 2.78 m
