Answer:
When a wave travelling in a medium is incident on
a boundary with another medium, a part of it
returns into the original medium with a change in
its direction of propagation while a part of it is
transmitted into the second mediun. The phenom-
enon in which a part of the wave is retumed into the
original medium with reduction in its intensity and
energy is called reflection.
