When a sound wave is reflected from a wall

When a sound wave is reflected from a wall the phase difference between the reflected and incident pressure wave is:
Answered by admin @
Answer:The phase difference will be 0° when a sound wave strikes the wall and is reflected back.Sound waves follow the reflection law which states that :
"The angle of the incident ray is equal to the angle of the reflection ray."
This behavior is observed for the light also. When reflected waves encounter incident waves,producing destructive and constructive interface.this could also lead to resonances in rooms called standing waves.
