In This post you will get answer of Q.
The width of the diffraction band varies
Solution:
Width of the diffraction band is given by
$ beta = frac{lambda D}{d} $
where D = distance between slit and the screen,
$ lambda = $ wavelength of light used and
$ $ d = width of slit.
Hence, width of the diffraction band varies directly as the distance between the slit and the screen.
