Sagot :
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 42.6 kHz, and the speed of sound in air is 323 m/s . The smallest insect a bat can detect will be of size 7.58 mm
wavelength = speed / frequency
as we know that a bat can detect small objects such as an insect whose size is approximately equal to one wavelength of the sound the bat makes hence , finding wavelength of the sound
wavelength = 323 / 42.6 * [tex]10^{3}[/tex] = 7.58 * [tex]10^{-3}[/tex] m or 7.58 mm
The smallest insect a bat can detect will be of size 7.58 mm
