waves travel from shallow water to deep question.?
waves travel from shallow water to deep. The angle of incidence is 20 degrees and the angle of refraction is 30 degrees . If the speed of the wave in shallow is 0.12m/s , what is the speed of the wave in deep water.

Per the rules of refraction, N1sin(theta1) = N2sin(theta2)
and v1/v2 = N2/N1
v1 = 0.12 m/s, theta1 = 20 deg, theta2 = 30 deg
Then v2 = v1N1/N2 = v1sin(theta2)/sin(theta1) = 0.1754 m/s
