## Answers ( )

1. Answer:

2.8m-3.4m

Explanation:

Radio waves are electromagnetic waves and they all travel with a speed of

in air.

The range of frequencies in the FM band is from 88MHz to 108MHz.

Generally, the relationship between velocity, frequency and wavelength for electromagnetic waves is given by equation (1);

From equation (1), we can write,

For the upper frequency of 108MHz, the wavelength is given by;

Similarly, for the lower frequency of 88MHz, the wavelength is given by;

The range of wavelength therefore  is approximately.
