11) Two very flat glass plates, 16 cm long, are in contact atone end and separated by 0.020 mm at the other end. The space between the plates isoccupied by oil with index of refraction 1.45. The refractive index of the glass plates is1.55. The plates are illuminated at normal incidence with monochromatic light, and fringes areobserved. If the spacing of the dark fringes is 2.0 mm, what is the wavelength of themonochromatic light? A) 425 nm B) 475 nm C) 525 nm D) 675 nm I already solved this question but I do not understand how thephase shifts work, how do you know if its one shift or two? Ithought It was two because light must get reflected when travelingfrom a low to high index of refraction and there are two glassplates to reflect light, overall I was told there was only onephase shift? why only one? . . .
