c) In a Young's double slit experiment, light of frequency 4.85 x 10¹4 Hz passes through a narrow single slit and is then incident on two very narrow, closely spaced, parallel slits. A screen is placed 1.60 m from the double slit arrangement and bright interference fringes are visible on the screen. The distance across 20 fringe spacings is 90.5 mm. Determine the spacing of the double slits. If the distance between the double slits and screen is reduced to 1.15 m, determine the spacing between adjacent dark fringes. i. ii. iii. If the monochromatic light source is replaced by an intense white light source, describe the appearance of the bright fringes closest to the centre of the screen.

HW9 Q7
A laser beam (λ=497 nm) is put through a beam splitter to give 2 equal intensity beams traveling parallel to one another. One of these beams is directed through a double slit apparatus, and the other beam through a single slit apparatus. The single slit and the double slits are in the same plane and both display fringe patterns on a screen a distance L= 3.3 m away. a. The slit spacing of the double slit apparatus is 0.63 mm. What is the distance from the center of the double slit fringe pattern to the 5th dark fringe? b. If the third dark fringe of the single slit pattern is the same distance from the center of the single slit pattern as the result for part (a), what is the single slit width? To continue, please enter the result of part b) in mm. Round your answer to 2 decimal places
