d. If '31 = 1.5 and '22 = 1.1 , what is the angle between the transmitted light ray and the original path of the incident light ray? 4. An object {the arrow) is placed at two different locations in front of a lens as shown in the diagram. The focal points of the lens are indicated by the black dots. a. What kind of lens is this? Explain how you can tell. b. Draw on the diagram two of the "easyto-draw" light rays coming from the tip of the object. Using the "easy-to-draw" light rays, clearly indicate on the diagram where the image forms. d. Is the images real or virtual? Explain how you can tell. 9 e.
