Textbook Question
Chapter 24.6, Problem 3cTH
Two thin convex lenses and an object are arranged as shown below. Two rays from the tip of the object are drawn in order to determine the location of the image produced by lens 1. Lens 2 is placed so that one of its focal points coincides with the location of the image produced by lens 1.
c. On the diagram above, clearly indicate:
• the direction in which the observer must look to see the tip of the image,
• the direction in which the observer must look to See the tail of the image, and
• an angle that represents the angular size of the entire image seen by the observer.
