Question 30 POST_UTME_UI • 2020 • PHYSICS • objective

A sound wave with frequency $f$ and amplitude $A$ is propagating through a medium with speed $v$. If the wave's intensity is given by $I = \frac{P}{A}$, what is the value of the power $P$ in terms of $f$, $A$, and $v$?

Correct Answer A. $ P = \frac{A^2 f^2}{v} $

B. $ P = \frac{A^2 f}{v} $

C. $ P = \frac{A^2 f^2}{v^2} $

D. $ P = \frac{A^2 f}{v^2} $

Correct Answer

Correct Option:

$ P = \frac{A^2 f^2}{v} $
