A bat receives a reflected sound wave from a fly. If the reflected wave returns to the bat 0.042 s after it is sent, how far is the fly from the bat? Would you expect the reflected wave pulse to be in or out of phase with the incident wave pulse? Explain.
here, Wave length founds to tn 7 m
as yhis is the integral value of L's
this is said to be in phase

When a sound wave travels directly toward a hard wall, the incoming and reflected waves can combine to produce a standing wave. There is an antinode right at the wall, just as at the end of a closed tube, so the sound near the wall is loud. You are standing beside a brick wall listening to a 85 Hz tone from a distant loudspeaker. Part A How far from the wall must you move to find the first quiet spot?...
6) If a plane wave is reflected from the ocean floor with a 15 dB reduction in amplitude angle of incidence of 30°, what are the possible values of the specific fluid bottom material if it has a speed of sound of 1666m/s? at an acoustic impedance of the 7) Calculate the amplitude and phase of the reflection coefficient for a plane wave incident on a sediment with density 1200 kg/m', sound speed 1700 m/s at an angle of incidence...
