Tennis is a racket sport played individually against a single opponent (singles) or between two teams of two players each (doubles). The objective of the game is to hit a ball over a net into the opponent’s court in such a way that they are unable to return it. Tennis is played on various surfaces, including grass, clay, and hard courts, each affecting the speed and style of play. Players use rackets with strings to strike the ball, and points are scored when the opposing player fails to return the ball within the designated court boundaries. The game proceeds in a sequence of games, sets, and matches, with players typically serving the ball to start each point. The sport is governed by specific rules and regulations, including the scoring system of points (love, 15, 30, 40, game) and rules regarding serves and faults. Tennis is highly popular worldwide, both as a recreational activity and a competitive sport, with professional tournaments such as the Grand Slam events (Wimbledon, US Open, French Open, and Australian Open).
