Answer 2

In the diffraction pattern of monochromatic light, the bright bands formed are (B) of non-uniform intensity.

• A diffraction pattern is formed of bright central maxima followed by alternate bright and dark fringes on either side of the central maxima.
• The intensity of the fringes keeps on decreasing as we go away from the central bright i.e. dark fringes become less dark and bright fringes become less bright.
• The width of the fringes also decreases successively.
• If monochromatic light is used, all the bright fringes are of the same color.
