The average power transmitted by a progressive wave in term of standard notations is

Options

A. `4pi^(2)A^(2)mu^(1//2)T^(-1//2)f^(2)`
B. `2pi^(2)A^(2)mu^(1//2)T^(1//2)f^(2)`
C. `2pi^(2)A^(2)muT^(1//2)f^(2)`
D. None

Explanation

`P_(av)=(1)/(2)(Tomega^(2)A^(2))/(V)`
where `V=sqrt((T)/(mu))` and `omega=2pif`.
