What is the wavelength for an FM radio signal if the number on the dial reads 101.8 MHz?

Answer 1

where "c" is the speed of light which is 2.998 x 10⁸ m/s, λ is the wavelength (in meters), and "f" is the frequency (in Hertz).

101.8 MHz = 101.8 x 10⁶ Hz =

So λ = (2.998 x 10⁸ m/s)/(101.8 x 10⁶ Hz) = 2.945 meters
