Question
In Young Double slit experiment maxima is observed at a fixed point P on the screen. Now the screen is continuously moved away from the plane slits. The ratio of intensity at point P to the intensity at point O (center of the screen)-


Options
A.Remains constant
B.keeps on decreases and then increases
C.First decrease and then increases
D.First decreases and then becomes constant
Solution
The maxima at P becomes minima & then maxima alternately. But central central bright fringe is always remains at O.
