In Young's double slit experiment, one of the slit is wider than other, so that amplitude of the light from one slit is double of that from other slit. If I m be the maximum intensity, the resultant intensity I when they interfere at phase difference φ is given by:

(D) I m /9(1 + 8 cos ² (φ)/2)

(B) I m /3(1 + 2 cos ² (φ)/2)

(C) I m /3(1 + 4 cos ² (φ)/2)
