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

  1. AI₀ ^2 ( x )
  2. BI₀ ^2 ( x )
  3. CI₀ 4 ^2 ( x )
  4. 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 )
