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

Intensity is given by Here and are same for both. And also given that is same for both. So pressure amplitude is also same for both |
