You are evaluating a method for studying liquid crystals. Two identical crystals are mounted overthe two slits of a double-slit apparatus. The slits are illuminated with monochromatic coherent lightand the interference pattern is observed on a screen. An electric voltage is then applied to one ofthe two crystals, causing its index of refraction to increase and the interference pattern to shift toone side. Your boss has asked you to calculate the change in the index of refraction of theelectrified crystal in terms of distance between the two slits, the distance from the slits to theobserving screen, the thickness of the crystals, the original index of refraction of the crystals (whennot electrified), the wavelength of the light used, and the distance that the central maximum of thepattern is observed to shift when the voltage is applied (you might not use all of these quantities inyour answer).two crystalsdouble slitsLightobserving screen
