What should be the slit-to-screen distance L (in meters) if the bright fringes are to be 5.2 mm apart? (A) 1.52 (B) 3.54 (C) 4.97 (D) 5.48 (E) 6.83 Problem 7. After a car is painted, a highly reflective coating is sprayed on to make the car look extra shiny. The index of refraction of the coating is less than the index of refraction of the paint underneath. 14. The minimum thickness needed for this coating is 100 nm. Find the index of refraction of this coating if it is highly reflective for a wavelength 2 = 510 nm, near the center of the visible spectrum. (A) 5.61 (B) 6.94 (C)3.56 (D) 4.89 (E) 2.55 Problem 8.
