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?

The wavelength of an electromagnetic wave is related to its frequency and its speed by the following relationship:

\lambda= (c)/(f)
where
c=3 \cdot 10^8 m/s is the speed of light, while f is the frequency of the wave.

In this problem,
f=1.5 \cdot 10^8 Hz, therefore the wavelength of the wave is

\lambda= (3 \cdot 10^8 m/s)/(1.5 \cdot 10^8 Hz)=2.0 m
