Vedclass · Answer

(C) speed gun used in cricket matches operates on the principle of the Doppler effect. It emits electromagnetic waves,specifically microwaves,towards the moving ball. When these waves reflect off the ball,their frequency changes due to the motion of the ball. By measuring this frequency shift,the speed gun calculates the velocity of the ball. Therefore,microwaves are the correct type of electromagnetic wave used for this purpose.

Which of the following waves is used in a speed gun to measure the speed of a ball in a cricket match?
