Red light of wavelength 633nm from a helium-neon laser passes through a slit 0.370mm wide. The diffraction pattern is observed on a screen 3.40m away. Define the width of a bright fringe as the distance between the minima on either side.
What is the width of the central bright fringe?
What is the width of the first bright fringe on either side of the central one?
