If a bat chirps at a frequency of 60000 Hz, and the speed of those waves are v=330 m/s, and the bat can detect insects 1 wavelength long, what is the smallest insect that it can detect in wavelengths?

In plain English, mosquitoes.

Hmm, this seems like a trick question. 1 wavelength?
Do you really mean that, because I could do some more math (I'm kind of addicted to this). For example, the wavelength is 330/60000 meters, so the smallest insect, in meters, is 33/6000 or a little less than half a centimeter

velocity = frequency * wavelength
v = f*lamda
330=60000*lamda
330/60000=lamda
this answer is in metres
