Tennis service should be sent in the following way. The service player shall stand before starting to serve, that is, stand behind the baseline (that is, the side away from the net), within the assumed extension line of the center mark and the sideline. Then the service player should throw the ball in any direction in the air with his hand and hit the ball with his racket before it touches the ground. At the moment when the racket contacts the ball, the whole transmission is considered to have ended. A player who can only use one arm can use his racket for throwing.

Tennis was conceived in France, born in Britain, and popularized and formed in the United States. It originated from France in the 12th and 13th centuries. At the first modern Olympic Games held in Athens in 1896, the men's singles and doubles of tennis were listed as official competitions.
