Question

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 ______.

विकल्प

• I₀ cos `(x/beta)`

• I₀ cos² `(x/beta)`

• I₀ cos² `((pix)/beta)`

• `("I"_0/4)cos^2 ((pix)/beta)`

Answer 1

In a Young's double-slit experiment, let β be the fringe width, and let 10 be the intensity at the central bright fringe. At a distance x from the central bright fringe, the intensity will be `underlinebb("I"_0 cos^2((pix)/beta))`.
