Question

A radio station broadcasts at a frequency of 1.5 x 10^8 Hz. The speed of an electromagnetic wave is a constant, 3.0 x 10^8 m/s. What is the wavelength of the radio wave?

a) 0.5 meters
b) 4.5 meters
c) 2.0 meters
d) 1.5 meters

Answer 1

The wavelength of the radio wave is 2.0 meters.

Step-by-step explanation:

The wavelength of a radio wave can be calculated by dividing the speed of light by the frequency of the wave. In this case, the frequency is 1.5 x 108 Hz, and the speed of light is 3.0 x 108 m/s. So, the wavelength is given by:

Wavelength = Speed of light / Frequency = (3.0 x 108 m/s) / (1.5 x 108 Hz) = 2.0 meters

Therefore, the wavelength of the radio wave is 2.0 meters (c).
