# Physics

Radio waves are electromagnetic waves that travel at a speed of 3.00 108 m/s, the speed of light. An AM radio station has an assigned frequency of 1350 kHz, which means that the radio waves broadcast by the station are at this frequency. Find the wavelength of these radio waves.

1. distance = speed * time
period = 1/frequency

L = 3*10^8 *(1/1.35*10^6)
= 2.22 * 10^2 = 222 m
