Intensity I 0 Two slit structures are illuminated by a monochromatic light of wave length λ=550nm. (a) (b) Find the slit separation d and width b from the figure (a) below. Describe the slit structure (number of slits, width b and separation d) giving rise to the interference pattern of Figure (b). Hint: Note that the first broad minimum (dotted line, defined by the slit width b) coincide with a minimum of the fast oscillating curve (defined by the slits separation d). Equating the condition on sine for the 2 coinciding minima gives the ratio d/b. 2- 0.001 0.002 0.003 0.004 0.005 0.006 (radians) (b) (a)
