What is the speed of radio waves?

Back

Radio waves travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second (186,282 miles per second).

Front

What is the relationship between wavelength and frequency in radio waves?

Back

The wavelength and frequency of radio waves are inversely related; as the wavelength increases, the frequency decreases, and vice versa.

Front

What are some common uses of radio waves?

Back

Common uses of radio waves include communication (radio and television broadcasting), radar, and wireless networking.
