Question

wave
why does velocity of
the wave reduces when it comes close to the shore?​

Answer 1

Explanation:

Remember that in deep water, a wave's speed depends on its wavelength, but in shallow water wave speed depends on the depth (section 10.1). ... When the wave touches the bottom, friction causes the wave to slow down. As one wave slows down, the one behind it catches up to it, thus decreasing the wavelength.
