What is Beamer in Cricket?

In Cricket terminology, When a Ball is delivered without bouncing over the waist height of the batsman when he is standing inside the crease then that delivery is termed as Beamer. This type of delivery may cause injury to Batsman.

Whenever a Bowler delivers Beamer Umpire warns at first instance, if the bowler delivers another beamer in the same innings then the Umpire suspends him from Bowling for the remaining innings.
