Relation Between Wave Velocity, Frequency, and Wave Length for a Periodic Wave
equation (1) can also be written as
v = ν λ ...(2)
Wave Velocity = Frequency × Wave Length Example : 1
If 50 waves are produced in 2 seconds, what is its frequency ? Solution.
= 50/2 = 25 Hz Example : 2
A source produce 50 crests and 50 troughs in 0.5 second. Find the frequency. Solution.
1 crest and 1 trough = 1 wave
∴ 50 crests and 50 troughs = 50 waves
