Question

Explain the reflection of the boundary of rarer medium

Answer 1

Answer:

At a Boundary of a Rarer Medium:

As the particles of air at the open end of a pipe are free to move, the surrounding air goes away quickly and compression is converted into a rarefaction before the wave is reflected. Thus, the compression after reflection at a rarer medium returns as a rarefaction
