Homework Help: Physics

1)The annoying sound from a mosquito is produced when it beats its wings at the average rate of 600 wingbeats per seconds. What is the wavelength? The speed sound in the air is 340 m/s.

I am not sure if I have to divide 600 by 340 to get 1.76 or do I divide 340 by 600 to get 0.567?

Wave Speed = (wavelength) x (frequency)

Therefore
Wavelength = (Wave speed)/(frequency
= (340 m/s)/600 s^-1 = 0.567 m
