Tennis: How is the speed of a tennis serve measured in tournaments?
In professional tennis tournaments, the speed of a serve is measured using a radar gun. The radar gun emits a microwave signal at the ball, and the time it takes for the signal to bounce off the ball and return to the gun is used to calculate the ball's speed. The radar gun is typically positioned behind the server, and it measures the speed of the serve as it travels over the net.
The speed of a serve is measured in kilometers per hour (km/h) or miles per hour (mph). The fastest serve ever recorded in a professional tennis match was 263 km/h (164 mph), hit by Samuel Groth at the Busan Open in 2012.
The speed of a serve is an important factor in tennis, as it can give the server an advantage in winning the point. A faster serve is more difficult to return, and it can also force the receiver to hit the ball back with less power.
