3. As part of an optical system, a thin lens has a power of 1.25 D. It is made of glass, with the first surface having radius 43.0 cm, as shown. The second surface is flat. (7 points) (a) Calculate the index of refraction of the glass. 43 cm (9 points) (b) This lens is used to create an image on a screen. If the image is to be 4.00 times the size of the object, calculate the distance to the screen. (9 points) (c) Construct and attach a ray trace to confirm your calculation in (b). (10 points) (d) This lens is used predominantly in the yellow-green part of the spectrum, with wavelengths in the range 540 nm <A < 580 nm. The lens needs an antiglare coating. If this coating is made of material with index 1.42, is a thickness less than 100 nm possible? Justify your answer.
