Question 15. When a compression is incident on rigid wall it is reflected as (a) Compression with a phase change of p (b) Compression with no phase change (c) Rarefaction with a phase change of p (d) Rarefaction with no phase change Answer
Therefore, a compression which is travelling towards the wall is reflected as a compression in the direction opposite to the wall and a rarefaction incident on the wall is reflected as a rarefaction.
