What is a player assigned when he/she serves a ball outside the service box

Answer 1

When a player serves a ball outside the service box in tennis, it is considered a fault. If the player then serves again, it's referred to as a second serve. If the player faults a second time (i.e., serves out of the service box again), it results in a double fault, and the opponent is awarded the point. In this context, the server must ensure that the ball lands in the correct service box for the serve to be valid.
