Question

FM radio waves have frequencies between 80.3 and 108 MHz. Determine the range of wavelengths for these waves.

Answer 1

c = Frequency * Wavelength

c = Speed of light = 3 * 10^8 m/sec

Input each frequency and the corresponding wavelengths will give you the wavelength range.

Answer 2

Wavelength(max(min) = ) = V/F = 3*10^8/80.3*10^6 = 3.74 m.

Wavelength(min) = V/F.
F = 108 MHz = 108*10^6 Hz.
