Evaluate the smallest insect a bat can detect

Reference no: EM13563293

A bat can detect small objects, such as an insect, whose sizeis approximately equal to one wavelength of the sound the batmakes. If bats emit a chirp at a frequency of 55.0 kHz, and if the speed of sound in air is 340m/s, what is the smallest insect a bat can detect?
