Answer:
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.

Two laws of refraction :-
The incident ray , refracted ray and the normal to the interface of two transparent media at the point of incidence, all line the same plane.
The ratio of sine of angle of incidence to the Sine of angle of refraction is a constant for the light of a given colour and for the given pair of media. This is also called Snell's law of reflection.
\boxed{\sf{sin I / sin R= constant}}
sinI/sinR=constant
