Question

What is the velocity of a deep-water wave if the wavelength is 30 meters and the period is 10 seconds?A. 0.3 meters/secondB. 3 meters/secondC. 30 meters/secondD. 300 meters/second

Answer 1

17

Step-by-step explanation:

Answer 2

B.3 m/s

Step-by-step explanation:

We are given that

Wavelength deep water wave=30 m

Time period=T=10 s

We have to find the velocity of deep water wave.

We know that the frequency=
`\\u=(1)/(T)`

`\\u=(1)/(10)=0.1 Hz`

Velocity, V=
`wavelength* frequency`

Substitute the values in the formula

Then, we get

Velocity of deep water wave=
`30* 0.1=3 m/s`

Hence, the velocity of deep water wave=3 m/s

Option B is true.
