- A monochromatic light of wavelength 800 nm is incident normally on a single slit of width 0.020 mm to produce a diffraction pattern on a screen placed 1 m away. Estimate the number of fringes obtained in Young's double slit experiment with slit separation 0.20 mm, which can be accommodated within the range of total angular spread of the central maximum due to single slit.

Single Slit Diffraction
In the single-slit diffraction experiment, we can examine the bending phenomenon of light or diffraction that causes light from a coherent source to hinder itself and produce an extraordinary pattern on the screen called the diffraction pattern.
