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 (called glare), which can make it difficult to see the art clearly. One solution is to coat the outer surface of the glass with a thin film to cancel part of the glare. Requried:
a. If the glass has refractive index of 1.62 and you use TiO2, which has a refractive index of 2.62 as the coating, what is the minimum film thickness that will cancel light of wavelength 505 nm?
b. If this coating is too thin to stand up to wear, what other thickness would also work? Find only the three thinnest ones.

An insulated thermos contains 148 g of water at 72.7 ˚c. you put in a 11.7 g ice cube at 0.00 ˚c to form a system of ice + original water. the specific heat of liquid water is 4190 j/kg•k; and the heat of fusion of water is 333 kj/kg. what is the net entropy change of the system from then until the system reaches the final (equilibrium) temperature?
