36. A monochromatic light that passes through a double slit produces on a screen a diffraction pattern consisting of bright and dark fringes. The intensity of the bright fringes, I, as a function of can be calculated by:

where and , is the light wave length, a is the width of the slits, and d is the distance between the slits.

Plot (as shown) the relative intensity as a function of y (distance to fringes on the screen) for cm given nm, mm, and mm.
