The laws of refraction and reflection are the same for sound as for light. The speed of sound in air is 340 m/s and in water it is 1510 m/s. If a sound wave approaches a plane water surface at an angle of incidence of 12.0, what is the angle of refraction?

Question 2

The index of refraction for red light in water is 1.331 and for blue light is 1.340 . If a ray of white light enters the water at an angle of incidence of 83.00, what are the underwater angles of refraction for the blue and red components of the light?
