Question 14 Light of 485 nm is shone through a diffraction grating to produce a diffraction pattern. a. [3] If the second order maxima occur at an angular position of 18.4", determine the number of lines (slits) per cm that the grating has. b. [2] Determine the angle at which the first-order dark fringe occurs. c. [3] An additional light source of wavelength A2 is shone through the grating. If the third order maxima of A₂ overlaps the fourth order maxima of the original light source (ie, the one with wavelength A₁), determine ₂. Total: 8 Marks
