Answer to Question #265208 in Physics for khorshed

Question #265208

Show that the sound wave intensity I can be written in terms

of the frequency f and displacement amplitude dm in the form, I = 2pi

vf ^2s^2 m.

Expert's answer

Energy of oscillation over time:

"\\frac ET=\\frac1{2T} mA^2(2\\pi f)^2."

Intensity is energy over area:

"I=2\\pi^2\\rho f^2vs^2."
