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 50.0 kHz, and if the speed of sound in air is 340 m/s, what is the smallest insect a bat can detect?

Answer 1

The smallest insect a bat can detect is approximately 6.8 mm in size. This is calculated by dividing the speed of sound (340 m/s) by the frequency of the chirp (50.0 kHz), which gives us 6.8 mm.
