Hello
When a mechanical wave gets reflected from a rigid surface,say a fixed end of a rope ,it undergoes a phase shift of ∏ ,but when a sound wave gets reflected from a hard surface ,say from a wall,it doesnt undergo any phase shift .
There is confusion regarding phase shift of sound wave from a hard surface,like a wall.At some places,I have read it doesnt undergo any phase change .At other places I have read ,sound undergoes a phase shift of ∏.
What is the correct explaination ?
Thanks
