Question

an observer standing at the sea coast observe 54 waves reaching the cost per minute if the wavelength of wave is 10 m then find the velocity of wave

Answer 1

the answer for your question is as follows

Answer 2

We know that,

Wavelength of the waves = distance travelled by the waves.

So,

One wave travels = 10 m

54 waves travel = 54×10 = 540 m

Now,

Velocity = Distance / Time

= (540/1 ) metre/minute

= (540/60) metre/second

= 9 m/s

So the velocity of those waves are 9m/s. (Answer)
