In Young’s experiment, monochromatic light is used to illuminate the two slits A and B . Interference fringes are observed on a screen placed in front of the slits. Now if a thin glass plate is placed normally in the path of the beam coming from the slit
A
The fringes will disappear 
B
The fringe width will increase
C
The fringe width will increase
D
There will be no change in the fringe width but the pattern shifts
Text Solution
Verified by ExpertsThe correct answer is:
D
In the presence of thin glass plate, the fringe pattern shifts, but no change in fringe width.
