Aperson fishing from a pier observes that 6 wave crests pass by in 8.0 s and estimates the distance between two successive crests to be 4.8 m. the timing starts with the first wave crest and ends with the last. what is the speed of the wave?

The speed of the wave is 3 m/s.

Explanation:

Given that,

Number of waves = 6

Time = 8.0 s

Successive crests

We need to calculate the frequency

Using formula of frequency

Put the value into the formula

We need to calculate the speed of the wave

Using formula of speed

Put the value into the formula

Hence, The speed of the wave is 3 m/s.
