A local radio station broadcasts at a frequency of 93.8 MHz with a wave length of 3.198 meters. What would be the speed of the radio wave?

Question

Quizplus · Accepted Answer

In this question, the frequency (93.8 MHz) and the wavelength (3.198 m) of the radio wave is presented.  
The velocity of a wave can be calculated by multiplying the frequency by the wavelength.
velocity = frequency * wavelength    or      v = f * λ
93.8 MHz means 93.8 Million Hertz
v = 93,800,000 * 3.198
v ~ 300,000,000 m/s
As we can see, the radio wave travels at the speed of approximately 300,000,000 m/s, which equals to the speed of light. Both the radio wave and light are electromagnetic waves, and they travel at the speed of light.
