Solution

A radio can tune to minimum frequency, ν1 = 7.5 MHz= 7.5 × 106 Hz

Maximum frequency, ν2 = 12 MHz = 12 × 106 Hz

Speed of light, c = 3 × 108 m/s

Corresponding wavelength for ν1 can be calculated as:

`lambda_1=c/v_1`

`=(3xx10^8)/(7.5xx10^6)=40m`

Corresponding wavelength for ν2 can be calculated as:

`lambda_2=c/v_2`

`=(3xx10^8)/(12xx10^6)=25m`

Thus, the wavelength band of the radio is 40 m to 25 m.
