Homework Help: PHYSICS - Waves

Posted by Diana on Tuesday, April 9, 2013 at 6:01pm.

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.

Sound waves with a wavelength of 2.5 m are traveling 7.5 m/s. How many waves will pass a microphone in 10.0 s? (Answer 30 waves)
