Question

Find the velocity of a wave of period 2 s and wavelength 0.5m. *

Answer 1

The velocity of wave is 0.25m/s

Step-by-step explanation:

First, you have to find the fequency using the formula, F = 1/Time :

`f = (1)/(t)`

Let t = 2s,

`f = (1)/(2)`

`f = 0.5Hz`

Next, you have to use speed formula, V = f×λ :

Let f = 0.5Hz,

Let λ = 0.5m,

`v = 0.5 * 0.5`

`v = 0.25`
