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]
