Last updated: 6/25/2023

In the figure shown sound waves A and B both of A wavelength are initially in phase and travelling rightward as indicated by the two rays Wave A is reflected from four parallel surfaces but ends up travelling in original direction The possible value s of distance L in terms of wavelength in figure which put A and B exactly out of phase with each other after all the reflections is are A 2 2 C 32 4 B 32 2 D 2 mih B
