Speed OF sound and reflection OF sound

Speed OF Sound||Reflection OF Sound

The laws of reflection or refraction are the same for sound as for light. The index of refraction of a medium (for sound) is defind as the ratio of the speed of sound in air 343 m//s to the speed of sound in the medium. What is the index of refraction (for sound) of water (v=1498 m//s) ? What is the critical angle theta , for total reflection of sound from water?

What name is given to the repettion of sound caused by the reflection of sound waves?
