The central bright fringe in a single slit diffraction pattern from the light having wavelength 513 nm is 2.2 cm broad on a screen which is 1.05 m from the slit.
(i) Determine how wide is the slit? (In mm)
(ii) Determine how broad are the first two bright fringes on either side of the central bright fringe? (State the width of a bright fringe as the linear distance from minimum to minimum.) Answer must be in cm.
