Question 5

# A radio can tune in to any station in the 7.5 MHz to 12 MHz band. What is the corresponding wavelength band?

Answer

A radio can tune to minimum frequency, ν_{1} = 7.5 MHz= 7.5 × 10^{6} Hz

Maximum frequency, ν_{2} = 12 MHz = 12 × 10^{6} Hz

Speed of light, c = 3 × 10^{8} m/s

Corresponding wavelength for ν_{1} can be calculated as:

Corresponding wavelength for ν2 can be calculated as:

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