Question

Hello!


Distance between crust & adjacent trough is 5 m. If the frequency of the wave is 50 cycle per second. What is its wave velocity

Answer 1

Distance between crust and adjacent trough will be : lambda/2

So, lambda /2=5m
lambda=10m

wave velocity = lambda × frequency
=10×50
=500m/s.

Answer 2

Distance between Adjacent Crest and trough is called Wave length.

Wave length is represented by λ

λ/2 = 5m
λ = 10m

Also Given Frequency ( n) = 50cycle/sec = 50Hz .

1 cycle per second = 1 Hz.

We know that,

Wave velocity ( v ) = n λ.

So,

v = 50 * 10 = 500m/s .

Therefore ,Wave velocity is 500 m/s
