NEET Physics Young's Double Slit MCQ Question
Consider a diagram showing a typical setup of Young's double slit experiment with two slits S1 and S2. If the distance between the slits and the screen is increased, what effect does it have on the fringe width observed on the screen?
The fringe width increases.
The fringe width decreases.
The fringe width remains constant.
The fringe width becomes zero.
Correct Answer
Detailed Explanation
According to the wave optics principles discussed in the context, the fringe width in Young's double slit experiment is directly proportional to the distance between the slits and the screen, so increasing this distance increases the fringe width.
