Explain reflection and refraction of waves.

Text Solution

Verified by Experts

"When a wave reaches to a boundary and if the second medium at boundary is rigid, then this wave will be returned back and it is called reflection of wave".
OR
"The phenomenon of returning back of wave from fixed support is called reflection.
Incident wave and reflected wave follow usual law of reflection.
Incident wave and reflected wave follow usual law of reflection.
If the boundary is not completely rigid or is an interface between two different elastic media, the effect of boundary conditions on an incident pulse or a wave is somewhat complicated. A part of the wave is reflected and a part is transmitted into the second medium.
If a wave is incident obliquely on the boundry between two different media the transmitted wave is called the refracted wave.
The incident and refracted waves obey Snell.s law of refraction.
