Can someone tell me how to get the answer to this question? Just a formula would be great. It's on my physics study guide for my unit test.

If 3 sound waves pass a microphone in 4.0 s while traveling 5.0 m/s, what is the wavelength of the waves? (6.67 m)

• PHYSICS - Waves -

L = V*T = 5m/s * (4/3)s = 6.67 m.

NOTE: 4/3 is the time for 1 wave.
