In Young's double slit experiment if the maximum intensity of light is Imax, then the intensity at path difference λ/2 will be A .Imax
B .2Imax
C .4Imax
D. None

Explanation:

When the path difference is half the wave length or λ /2 , destructive interference takes place which results in reduced or zero intensity in case equal intensity waves interfere as in Young's double slit experiment

Hence dark fringe is formed at that place where intensity is zero .

Hence the right option is D

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!

the answer is a. hope this .
