The Laws of Refraction and Reflection Are the Same for Sound

question 10

Short Answer

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 $\degree$ ,what is the angle of refraction?
