The basic technology used, is the Doppler Effect.
Basically it measures the change in the frequency of the wave for any object moving relative to the source.
Sometimes during the US Open, you can see some person caryying a small antenna like instrument and wearing a big earphone (especially when the player is serving, you can see him at the far corner).

The tennins, Wimbledon common, Shopps and the wimbledon windmill on the Wimbledon Common
The fastest serve ever recorded at the Wimbledon Championships was 148 mph, achieved by Taylor Dent in 2010.
Roemer was the first to measure the speed of light.
To measure the speed of a wave, you multiply the frequency by the wavelength.
Speed is the measure of distance over time.
Well wimbledon is called wimbledon because its in wimbledon and secondly why do you need to know this. Then it will make it easier for me to answer
