1. You have been tasked with designing an antireflective coating for a camera lens.

a) If the material you are using for the thin film, the antireflective coating has an n=1.38, and a coating is designed to eliminate reflected light of 550 nm in air when incident normally on glass (n=1.50), what thickness should the film be?

b) Why does this effect indicate that light behaves like a wave?

c) What "color" would the lens look like. Explain?

2. a) For a converging lens with a focal length f drawn a ray diagram on scale for an object located at 1/2 f in order to find the image. from your scale diagram estimate the magnification of the converging lens.

b) What should the image distance and magnification be, i.e. determine the image distances' using the thin lens equation, and also calculate the magnification?
