A manufacturer wants to improve the performance of a  battery pack by reducing the amount of light reflected from its surface. You suggest applying a thin film of material with an index of refraction = 1.42 can help. These particular solar cells rely on light with a wavelength (in air) λ = 250 nm. The index of refraction of the material below the thin film is greater than 1.42. What are the phase shifts at the upper and lower boundries? What...
