1. monochromatic light of wavelength 540 nm from a source passes through a slit that is 0.03mm wide. What is the width of the central bright fringe on the diffraction pattern formed on a screen placed at a distance of 2.00 m away from the slit?

2. Light of wavelength 500 nm is incident on a single slit of width 0.02 mm to produce a diffraction pattern with intensity 4.00×10^-4 W/m^2 at the center of a screen placed far away from the slit. Calculate the intensity of the light at a point corresponding to orientation 2.4 degrees
