In Young's double slit experiment of central fringe is I₀ and fringe width is . If a point is at a distance x from the central fringe, then the intensity at that point is
Options
- AI₀ ^2 ( x )
- BI₀ ^2 ( x )
- CI₀ 4 ^2 ( x )
- DI₀ ^2 ( x )
Correct answer
A. I₀ ^2 ( x )
Step-by-step solution
Intensity at distance x from central maximum is given by I=4 I₀ ^2 2 where, = 2 d Also, = D d Combining these, we get I=I₀ ^2 ( x )
