Problem

In YDSE, with slits of equal width, let

\beta

be the fringe width and

I_0

be the maximum intensity. At a distance

x

from the central bright fringe, the intensity is (1)

I_0\cos\left(\frac{x}{\beta}\right)

(2)

I_0\cos^2\frac{2\pi x}{\beta}

(3)

I_0\cos^2\frac{\pi x}{\beta}

(4)

\frac{I_0}{4}\cos^2\frac{\pi x}{\beta}
