Answer:
Reflection=The process of sending back light rays which fall on the surface of an object, is called reflection of light. A plane mirror reflects almost all the light which falls on it. In order to study the reflection of light, we need an apparatus which can produce a thin beam of light.
Diffraction=Diffraction refers to various phenomena that occur when a wave encounters an obstacle or opening. It is defined as the bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture.
