Answer» Two differences between interference and diffraction are as follows— Interference 1. It is due to the super position. 2. In interferance patter, the dark fringes are usually almost perfectly dark. Diffraction 1. It is due to the super position of secondary wavelets originating from the different points of the same wave front. 2. In diffraction pattern, the dark fringes are not perfectly dark. |
