In the Young's double slit experiment as shown in the figure, 
is the path difference between waves at a point on screen. Now, a thin transparent glass sheet is introduced infront of 
which absorbed 
of light incident on it.
Match the Column I with Column II .
Column I | Column II | ||
(A) | Intensity of maxima will | (I) | Increase |
(B) | Intensity of minima will | (II) | Decrease |
(C) | Fringe width will | (III) | Remains same |
(D) | Fringe pattern will | (IV) | Shift downward |
Choose the correct answer from the options given below.

Before introducing transparent sheet, intensity of
maxima is 
. After introducing transparent sheet, intensity of maxima is
Thus, intensity of maxima will decrease.
Before introducing transparent sheet, intensity of minima is zero. After introducing transparent sheet, intensity of minima is 
Fringe width, 
. Hence, it remains unchanged.
Since, transparent sheet is used infront 
, so fringe pattern will shift downward.
Hence, A-(II), B-(I), C-(III), D-(IV).
