Write two points of difference between interference and diffraction.
Write two points of difference between interference and diffraction.

Ans: Some differences between interference and diffraction are the following:
\begin{tabular}{|l|l|}
\hline \multicolumn{1}{|c|}{ Interference } & \multicolumn{1}{c|}{ Diffraction } \\
\hline Interference occurs due to & It is due to the superposition of the \\
superposition of light coming & waves coming from different parts \\
from two coherent sources. & of the same wave front. \\
\hline All bright fringes are of equal intensity. & The intensity of bright fringes decreases with increasing distance \\
& from the central bright fringes. \\
\hline
