Question

In Young's double slit experiment, then monochromatic light is used to illuminate two slits A and B as shown. Interference fringes are observed on a screen placed infront of slits. Now if a thin glass plate is placed normally in the path of beam coming from the slit A then(a) there will be no change in fringe width(b) fringe width will decrease(c) fringes will disappear(d) fringe width will increase

Answer 1

A if a transparent glass is simple

Answer 2

Answer:

here u go

Explanation:

When we put a glass plate in the path of one of the beams interfering with each other then there is change of place of fringes on the screen. All the fringes including central fringe are shifted. It does not result in change of fringe width.
