Question

An FM radio station broadcasts electromagnetic radiation at a frequency of 101.7 MHz. The wavelength of this radiation is ________ m.

Answer 1

We know that frequency, = c / λ

Where

c = speed of light = 3x 10⁸ m/s

= frequency = 101.7 MHz = 101.7x10⁶ Hz

λ = wave length = ?

Plug the values we get λ = c /

                                    = (3x 10⁸ m/s) / (101.7x10⁶ )

                                    = 2.95 m

Therefore the wavelength of this radiation is 2.95 m
