In a Young’s double slit experiment, let β be the fringe width, and let I0 be the intensity at the central bright fringe. At a distance x from the central bright fringe, the intensity will be
- \(I_{0} \cos \left(\frac{x}{\beta}\right)\)
- \(I_{0} \cos ^{2}\left(\frac{x}{\beta}\right)\)
- \(I_{0} \cos ^{2}\left(\frac{\pi x}{\beta}\right)\)
- \(\left(\frac{I_{0}}{4}\right) \cos ^{2}\left(\frac{\pi x}{\beta}\right)\)
Answer
(C) I_ 0 ^ 2 ( x )
