2 sound waves in the same direction have average power transmitted in the ratio 1:1
Also ration of their wavelengths lambda1/lambda2 = 1:2
Find ratio of their pressure amplitudes
P1/P2 = A1^2 f1^1 / (A2^2 f2^2)
1 = (A1^2/A2^2) (lambda2^2 / lambda1^2)
So (A1^2/A2^2) = 1/4 or A1/A2 = 0.5
wht is the formula for average power transmitted??
