To find: The minimum velocity of the length of the wave.
The minimum velocity of the length of the wave is
The velocity of a wave of length L in deep water is
Consider the velocity of a wave,
Where k and C are the positive constants,
Then derivation of V with respect to L,
Length L is a positive quantity so
And when or
So V has an absolute minimum at
