L = V*T = V/F = 30
F = V/L = 7.5/2.5 = 3 Hz = 3 cycles/s.
3cycles/s * 10s = 30 Cycles or waves.
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)
