How the speed of the ball is measured in cricket |
| Answer» Measuring the velocity of the ball through Radar Guns or Speed Guns is\xa0like measuring the speed of the moving car. This technique was\xa0discovered in 1947 by "John Baker". Speed gun works on the principle of Doppler Effect. This Speed Gun has a receiver and a transmitter.The Speed Gun is placed on a high pillar near the Sight screen, from which Speed Gun sends radio wave in the direction of the pitch and calculates the speed of any object on the pitch.\xa0OrRadar Gun, which\xa0works on a similar principle of SONAR, catches the echo of Radio waves as the ball travels through the air, and uses a principle called "Doppler Shift".The information obtained through Speed Gun is inserted into image processing software, which identifies the ball between other objects on the pitch and displays the speed of the ball. | |
