A bat emits a sound whose frequency is 82.2 kHz. The speed of sound in air at 20.0 oC is 343 m/s. However, the air temperature is 37.3 oC, so the speed of sound is not 343 m/s. Assume that air behaves like an ideal gas, and find the wavelength of the sound.

A room contains air in which the speed of sound is 343 m/s. The walls of the room are made of concrete, in which the speed of sound is 1 850 m/s.

(a) Find the critical angle for total internal reflection of sound at the concrete–air boundary.

(b) In which medium must be the sound be initially traveling if it is to undergo total internal reflection?

(c) "A bare concrete wall is a highly efficient mirror for sound" Give evidence for or against this statement.
