Question

A radio station broadcasts at a frequency of 1.5 × 108 hz. the speed of an electromagnetic wave is a constant, 3.0 × 108 m/s. what is the wavelength of the radio wave?

Answer 1

The relationship between frequency and wavelength for a wave is given by:

`\lambda= (c)/(f)`
where

`\lambda` is the wavelength
c is the speed of light
f is the frequency

Using the data of the problem, we can find the wavelength of the radio wave:

`\lambda= (3 \cdot 10^8 m/s)/(1.5 \cdot 10^8 Hz)=2 m`
