$We define the index of refraction of a material for sound waves to be the ratio of the speed of sound in air to the speed of sound in the material. Snell's law then applies to the refraction of sound waves. The speed of a sound wave is 344 m / s in air and 1320 m / s in water. (a) Which medium has the higher index of refraction for sound? (b) What is the critical angle for a sound wave incident on the surface between air and water? (c) For total internal reflection to occur, must the sound wave$

$Sound waves can be used to perform a nondestructive angle beam inspection of a weld. In the figure shown, SD is the surface distance between two reflection nodes, T is the thickness of the material, and θis the refraction angle of the sound beam. If cosθ=(5)/(7) and the material is 1.5 cm thick, determine the length of the sound path in the material to the first node, L1, and the surface distance, SD. | Numerade$
