    When viewing a piece of art that is behind glass, one often is affected by the light that is reflected off the front of the glass (glare), which can make it difficult to see the art clearly. One solution is to coat the out surface of glass with a film to cancel part of the glare. a.) if the glass has a refraction index of 1.62 and you use TiO_2, which has an index of refraction of 2.62, as the...

    Question 15 5 pts A thin layer of magnesium fluoride (n = 1.38) is applied to the outer surface of a glass (n = 1.52) camera lens as an anti-reflective coating. When viewed from a direction that is nearly perpendicular to the lens in white light, the lens appears slightly green in color, since it only reflects light with a wavelength in vacuum of 540 nm. Based on this information, what is the smallest nonzero thickness of the magnesium fluoride...
