Question

A radio wave, a form of electromagnetic wave, has a frequency of 106.5 MHz what is the wavelength

Answer 1

f: frequency

λ: wavelength

c: speed of light

f = 106.5 MHz = 106.5*10^6 Hz

c = 3*10^8 m/s

Equation we need:

fλ = c

106.5*10^6 Hz * λ = 3*10^8 m/s

λ = (3*10^8)/(106.5*10^6)

λ = 2.8169 m
