Respuesta :
Because if the velocity decreases then the frequency and wavelength would be affected since frequency deals with how fast the wave is going and since shallow water is lower theres not many waves to continue the movement of the wave
Explanation:
As ocean waves approach shore, their velocity decreases. The relation between the velocity, wavelength and the frequency of a wave is given by :
[tex]v=f\times \lambda[/tex]
f = frequency
[tex]\lambda[/tex] = wavelength
[tex]f=\dfrac{v}{\lambda}[/tex]..............(1)
So, as the velocity of the wave increases, the wavelength and frequency also increases as per equation (1). When the velocity decreases, the frequency and the wavelength also decreases.
