A broad beam of monochromatic light is directed perpendicularly through two glass plates that are held together at one end to create a wedge filled with a certain gas between them. An observer intercepting light reflected from the wedge of gas, which acts as a thin film, sees 4792 dark fringes along the length of the wedge. When the gas between the plates is evacuated, only 4791 dark fringes are seen. Calculate the index of refraction of the gas from these data.
