A fisherman sees 7 wave crests go by in 10.0 s. The crests are 2.43 m apart. Find the period of the wave. (Unit = s)​

Sagot :

Velocity of the wave is 1.7 m/s

Explanation:

As we know that the frequency of the wave is defined as the number of waves crossing a fixed point per second

So here we will have

Also we know that the distance between two consecutive crest or two consecutive trough is known as wavelength

So here the wavelength of the wave is given as

now we have

The wave period will be 1.42 s.

What is wave period?

The time interval, expressed in seconds, separating two waves as they pass throughout a stationary point has been known as the wave period.

What is wave?

A pulse seems to be a single disturbance, whereas a wave would be a persistent, repeated interruption of a medium.

Calculation of wave period

The frequency = 7 / 10 = 0.7 Hz

Wave period can be calculated by the formula:

Wave period = 1 / frequency

Put the value of frequency in above equation.

Wave period = 1 / 0.7

Wave period = 1.42 s

Therefore, the wave period will be 1.42 s
