Question
Consider the arrangement shown in figure. By some mechanism, the separation between the slits 
and 
can be changed. The intensity is measured at the point P which is at the common perpendicular bisector of 
and 
. When 
, the intensity measured at P is I. Find this intensity when z is equal to
1) 
,
2) 
, and
3) 
.
- O,I,2I
- I,O,2I
- 2I,O,I
- I,2I,3I
The correct answer is: O,I,2I
