Or
(i) In Young's Double Slit Experiment describe briefly how bright
and dark fringes are obtained on the screen kept in front of a
double slit. Hence obtain the expression for fringe width
(ii) Two slits are made one mm apart and the screen is placed one
metre away. Find fringe width when blue light of wavelength
500nm is used?​

Answer:

When light waves from two illuminated slits is incident on the screen, the path traveled by each light wave is different. This path difference leads to a phase difference in the two light waves. The path difference is different for each point on the screen and hence, intensity is different for all the points. This leads to the formation and bright and dark fringes on the screen.
