In Young's double slit experiment, one of the slits is wider than the other, so that the amplitude of the light from one slit is double that of the other slit. If interference fringes are observed on a screen placed at a distance D from the slits, What will be the ratio of the maximum intensity to the minimum intensity of the fringes?
1) 1:2
2) 1:4
3) 1:8
4) 1:16
