Question:
Radio waves travel at the speed of light, which is {eq}3.00 \times 10^8\ \rm m/s {/eq}. What is the wavelength for a FM station broadcasting at {eq}105.9\ MHz {/eq}?
Wave Equation
One of the basic wave equations relates to the speed of the wave, the wavelength of the wave and the frequency of the wave is used to solve such a problem, or if the frequency of wave remains constant then wave speed is directly proportional to the wavelength of the light.
