Question
The average power transmitted by a progressive wave in term of standard notations is
Options
A.4π2 A2 μ1/2 T–1/2 f 2
B.2π2 A2 μ1/2 T1/2 f 2
C.2π2 A2 μ T1/2 f 2
D.None
Solution
Sol. Pav = $\frac{1}{2}\mu A^{2}\omega^{2}\nu^{2}$
= $\frac{1}{2}\mu A^{2}4\pi^{2}f^{2}\sqrt{\frac{T}{\mu}}$ = 2π2A2μ1/2 T1/2 f2
