What will be the angle of diffraction for the first secondary maximum due to diffraction at a single slit of width 0.5 mm and using light off 5000 Å?

(a) Derive the relation a sin theta=lambda for the first minimum of the diffraction pattern produced due to a single slit of width ‘a’ using light of wavelength lambda . (b) State with reason, how the linear width of central maximum will be affected if (i) monochromatic yellow light is replaced with red light, and (ii) distance between the slit and the screen is increased. (c) Using the monochromatic light of same wavelength in the experimental set-up of the diffraction pattern as well as in the interference pattern where the slit separation is 1 mm, 10 interference fringes are found to be within the central maximum of the diffraction pattern. Determine the width of the single slit, if the screen is kept at the same distance from the slit in the two cases.

The first diffraction minima due to a single slit diffraction is at q = 30^(@) for a light of wavelength 5000 Å. The width of the slit is-
