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

Answer:

17

Explanation:

Answer 2

Answer:

B.3 m/s

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=$\nu=\frac{1}{T}$

$\nu=\frac{1}{10}=0.1 Hz$

Velocity, V=$wavelength\times frequency$

Substitute the values in the formula

Then, we get

Velocity of deep water wave=$30\times 0.1=3 m/s$

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

Option B is true.
