Question
In Young′s double slit experiment , on of the slits painted that intensity of light emitted from it is half of that of the light emitted from other slit. Then
Options
A.fringe system will disappear
B.bright fringes will becomes brighter and dark fringes will darker
C.both bright and dark fringes will becomes darker
D.dark fringes will become less dark and bright fringes will becomes less bright.
Solution
For maxima, Imax = (√I1 + √I2)2
When I1 = I2 then Imax = 4I
For minima Imin = (√I1 + √I2)2 Imin = 0
I2 =
, them Imax = 
< 4I1.
I′min =
> Imin
When I1 = I2 then Imax = 4I
For minima Imin = (√I1 + √I2)2 Imin = 0
I2 =
, them Imax = < 4I1.I′min =
> IminCreate a free account to view solution
