Question

Write two improtant condition to observe diffraction of light

Answer 1

Diffraction is a phenomenon that occurs when light comes across an object and is obstructed. The essential condition for diffraction to occur is that the wavelength of light should be comparable to that of the size of the object. It might also occur if the size of the object is less than the wavelength of light.

Answer 2

to observe a diffraction pattern the obstacle must be very small so that the light bends around the obstacle and secondly the light incident on the obstacle should be monochromatic and very bright and at the last the screen must be placed at a finite distance
