A bat can detect small objects, such as an insect, whose size is approximately equal to one wavelength of the sound the bat makes. If bats emit a chirp at a frequency of 60.0 x 10³ Hz and the speed of sound in air is 343 m/s, what is the smallest insect a bat can detect?

1) A bat flying at 4.00 m/s is chasing an insect flying in thesamedirection. If the bat emits a 40.0-kHz chirp and receives backanecho at 40.4 kHz, what is the speed of the insect? (Take thespeedof sound in air to be 340 m/s.)

2) The acoustical system shown in the figure below is driven byaspeaker emitting sound of frequency 732 Hz. (Take the speedofsound as 345 m/s.)

(a) If constructive interference occurs at a particular instant,bywhat minimum amount should the path length in the upperU-shapedtube be increased so that destructive interferenceoccursinstead?

(b) What minimum increase in the original length of the uppertubewill again result in constructive interference?

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.
