Question

The average power transmitted across a cross section by two sound waves moving in the same direction are equal. The wavelength of two sound waves are in the ratio of `1:2`, then find the ratio of their pressure amplitudes.

Answer 1

Intensity is given bt `I=(p_0^2)/(2rhov)`.
Here v and `rho` are same for both. And also given that `I` is same for both. So pressure amplitude is also same for both
