Question

Plane waves in the ripple tank undergo refraction when they move from deep to shallow water. what change dose occur in the speed of the waves??? ​

Answer 1

When they move from deep to shallow water there is an increase in the speed of the wave.

Explanation:

• this is because the refractive index of deep water is more as compared to that of the shallow water. As we know that refractive index is inversely proportional to the speed of that light in particular medium.
• Hence there will be increased in the speed of light. Also there will be movement of water away from the normal when incident at the surface between deep water and shallow water.

Answer 2

Answer:

the speed of water waves will decrease

Explanation

Water waves travel fastest when the medium is the deepest. Thus, if water waves are passing from deep water into shallow water, they will slow down. So as water waves are transmitted from deep water into shallow water, the speed decreases, the wavelength decreases, and the direction changes. The wavelength will decrease but the frequency won't increase as it'll be always equal to the frequency of the vibrator in ripple tank.
