Question

this looks really easy but i do not understand wat you do to get the answer.....

The sound emitted by bats has a wavelength of 3.7 mm. What is the sound's frequency in air?

___Hz

Answer 1

Well first you need the speed of sound which is 343 m/s.

You then use the formula f=v/w

f is frequency

v is speed

w is wavelength

f = 343/.0037

92700 Hz

which could also be written as 92.7 kHz
