The diagram shows 2 out of the 3 possible principal rays traversing a thin lens of unknown type. The focal points are labeled F1 and F2, the object is at 0, and the image is at I. Which is the correct description for the missing third principal ray? Select one: C a. From the tip of the object draw a ray going through F1; as it crosses the lens it emerges going through F2. C b. From the tip of the object draw a ray through F1. As this ray crosses the lens, it emerges parallel to the optical axis C c. From the tip of the object draw a ray toward the lens, parallel to the optical axis; as it crosses the lens it refracts going through F2. O d. From the tip of the object draw a ray through the center of the lens. As it crosses the lens it continues without changing direction. Ce. From the tip of the object draw a ray going through the center of the lens and it emerges parallel to the axis. Check
