Maria asks…Doppler Effect?Please help with the following question:
A "radar gun" is often used to measure the speed of a major league pitch by reflecting a beam of radio waves off a moving ball. Describe how the Doppler Effect can give the speed of the ball from a measurement of the frequency of the reflected beam.
For sound waves that propagate in a wave medium, the velocity of the observer and the source are measured relative to the medium in which the waves are transmitted. The total
