Question

In a single slit diffraction experiment, the width of the slit is made double the original width. How does this affect the size and intensity of the central diffraction band? Draw a plot of intensity distribution.

Or

Draw the diffraction pattern due to a single slit by a monochromatic light.

Answer 1

The size reduces by half according to the relation:

Size = \(\frac{\lambda}{d}\)

Intensity increases four fold. The intensity distribution graph is shown in Fig.
