Q. When a radar gun utter the pitch is 90 miles per hour at what point in the balls travel to home plate is the radar gun measuring the velocity?
Answer:-
The measurement is complete at the point where the ball is when the trigger is squeezed as well as the contacts close to activate the unit. The gun responds in a split second by sending out a pulse catching the return as well as then comparing the two to discover the difference (the Doppler shift). It is thus fast that the ball does not travel very far in the time it takes the unit to respond and resolve the speed.
