Edited sentence: A good length ball or salmon ball is one that arrives at the batsman at around waist height.Because the three effective lengths (good length, bouncer and yorker) are all interspersed by lengths that are easy for the batsman to hit, control of length is an important discipline for a fast bowler.If the ball fails to bounce at all before reaching the batsman it is labelled a full toss or beam ball.If this doesn't work, the fast bowler tries to break the batsman's toe along with the stumps, in order to please the score books.It is very easy for a batsman to play such a delivery as it has not deviated from bouncing off the pitch.Needless to say that is tough to do and needs a lot of discipline and luck.Often, when the fast bowler is angry, he resorts to a bouncer, in which the bowler aims at the batsman's head off with a short-pitched delivery
