Question

A series of ocean waves, each 5.0 m from crest to crest, moving past the observer at a rate of 2 waves per second. What is the velocity of ocean waves?

• A. 2.5 m/s
• B. 5.0 m/s
• C. 8.0 m/s
• D. 10.0 m/s

Answer 1

The correct option is D 10.0 m/s

Here wavelength of the waves is given as

$\lambda =5.0$ m.

Frequency $\nu =2$

Wave velocity $v=\nu \lambda =10$ m/s.
