Sound passes from limestone, where it moves at a speedof 4000 m/s, into another unknown material. The angle of incidence at the interface is 24° and the angle of refraction in the unknown material is 38°. (a) Calculate the speed of sound in this material. (b) Draw pictures of each situation showing the interference between the media, the normal line, the incident, reflected and refracted rays and the angles of these rays to the normal line.
