What is a let serve in badmninton?

A let serve in Badminton occurs when the serve is interrupted or needs to be replayed due to specific circumstances, such as the shuttlecock hitting the net but still landing in the correct service area. It can also be called if the receiver is not ready, or if there is any external interference. In such cases, the server will redo the serve without any penalty. The point is not awarded to either player.
