Question

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
​

Answer 1

Step-by-step 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
