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

Respuesta :

Answer:

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

[tex]f = \frac{N}{t}[/tex]

[tex]f = \frac{7}{10} = 0.7 Hz[/tex]

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

[tex]\lambda = 2.43 m[/tex]

now we have

[tex]v = \lambda \times f[/tex]

[tex]v = (2.43 \times 0.7)[/tex]

[tex]v = 1.7 m/s[/tex]
