If the wave of water moving from district to district, deep water and shallow water wave-cut in half. Find the ratio of the speed of waves in deep water with the speed of waves in shallow water.
If water waves moving from the deep water to shallow water. Then wavelength halved. What is the ratio of the speed of the waves in deep water with the speed of a wave in shallow water.
If the wave moving water from deep water to shallow water area area. Make wavelength is reduced by half. Find the ratio of the speed of waves in deep water with the speed of waves in shallow water.
