Interference and Diffraction





Interference refers to the phenomenon where two waves of the same kind overlap to produce a resultant wave of greater, lower, or the same amplitude. 

Diffraction is defined as the bending of a wave around the corners of an obstacle or aperture.

Interference may be defined as waves emerging from two different sources, producing different wave fronts while Diffraction on the other hand can be termed as secondary waves that emerge from the different parts of the same wave.



In interference the intensity of all the positions on maxima are of similar intensity in interference while In diffraction, there is a variance of the intensity of positions.

If the number of sources is few such as two sources, then they are referred to as interference sources while if the number of sources is many, that is more than two then it is referred to as diffraction sources.
