Red light of wavelength 633 nm from a helium-neon laser passes
through a slit 0.350 mm wide. The diffraction pattern is observed
on a screen 2.55 m away. Define the width of a bright fringe as the
distance between the minima on either side.
a) What is the width of the central bright fringe?
b) What is the width of the first bright fringe on either side
of the central one?

Red light of wavelength 633 nm from a helium-neon laser passes
through a slit 0.400 mm wide. The diffraction pattern is observed
on a screen 3.25 m away. Define the width of a bright fringe as the
distance between the minima on either side.

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...
