What is a double in volleyball?

In volleyball, a double is a type of violation that occurs when a player contacts the ball twice in succession during a single play. This can happen when a player attempts to set the ball, but accidentally makes contact with it twice using either their fingers or their hands.

Doubles are often called by the referee when the ball seems to come to a stop or change direction after being contacted by a player. This violation typically results in the opposing team being awarded a point or the right to serve.

It is important for players to be aware of the rules and techniques for setting the ball in order to avoid committing a double violation. Double violations can be avoided by using proper technique, such as making sure that the hands are facing upwards and contacting the ball cleanly with the fingertips.
