Question

Explain diffraction of light due to a narrow single slit and the formation of pattern of fringes on the screen.​

Answer 1

Answer:

Single slit diffraction is explained by treating different parts of the wave front at the slit as sources of secondary wavelets. At the central point C on the screen, θ is ''zero''. All path differences are zero and hence all the parts of the slit contribute in phase and give maximum intensity at C.
