Define angle of repose
Consider a body resting on a plane OA. Assume this plane OA is slowly raised from the horizontal position to incline it with the horizontal.
Will there be any change in hz of sound if two vibrating body has the similar hz Ans) Yes it depends on the path difference among them... Like in destructive inteference u
