The FM radio band in most places goes from frequencies of about 89 MHz to 106 MHz. How long is the wavelength of the radiation at the beginning of the range

2.83 m

Explanation:

The relationship between frequency and wavelength for an electromagnetic wave is given by

where

is the wavelength

is the speed of light

is the frequency

For the FM radio waves in this problem, we have:

is the minimum frequency, so the maximum wavelength is

The maximum frequency is instead

Therefore, the minimum wavelength is

So, the wavelength at the beginning of the range is 2.83 m.
