Sound Intensity and Power
At a distance of 3.8 m from a siren, the sound intensity is 3.6 x 10^-2 W/m^2. Assuming that the siren radiates sound uniformly in all directions, how do you find the total power radiated?
The intensity of a sound wave is its power/unit area.
I = P / A
Now the ...
This solution uses the equation for sound intensity and sphere to determine the total power radiated from the siren. All steps are shown with brief explanations.
