I've looked throughout my book for the formula, and I've looked online to see if there were similar problems so I could figure out how to do this, but I can't find anything.

A bat can detect small objects, such as insects, whose size is approx. equal to one wavelength of the sound the bat makes. If bats emit a chirp at a freq. of 59 kHz, and if the speed of sound in air is 340m/s, what is the smallest insect (mm) a bat can detect?
Maybe it's easier than I think. I'm definitely not a physics person. I'm not asking for the answer, just some help in find the right equation :)
Thanks for any help.
