# If one of two identical slots producing interference in youngs experiment is covered with glass so that the light intensity passing through it is reduced to 50% find the ratio of the maximum and minimum intensity of the fridge in the interference pattern.

I1/I2 = 2
Imax/Imin = [($\sqrt{I_{1}^{}}$ +$\sqrt{I_{2}^{}}$)/($\sqrt{I_{1}^{}}$$\sqrt{I_{2}^{}}$)]2 = [($\sqrt{I_{2}/I_{1}}$ +1)/($\sqrt{I_{2}/I_{1}}$ – 1 )]2
= [(2+1)/(2-1)]2 = 9.
