A bat see the image below can detect very small objects, Ask an Expert

Academics

A bat (see the image below) can detect very small objects, such as an insect whose length is approximately equal to one wavelength of the sound the bat makes. If bats emit chirps at a frequency of 59.3 kHz, and if the speed of sound in air is 336 m/s, what is the smallest insect the bat can detect?
