1. Figure below shows a double slit located a distance x from a screen, with the distance from the center of the screen given by y. The slits are illuminated by light of wavelength A. When the distance d between the slits is relatively large, there will be numerous bright spots, called fringes. Using the small angle approximation (where sin88, with 8 in radians), calculate the distance between fringes in terms of A and the variables shown below. d m+1 cm X ym Ym+1 Answer symbollically using. x,d, and λ. Use the orange square root symbol box to enter variables and greek symbols. Ay= Using the result of part (a), calculate the distance between fringes for 679 -nm light falling on double slits separated by 0.095 mm, located 3.5 m from a screen as in Figure. ду.
