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

Question
![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 O, and the image is at I.
(Graph/Diagram Description)
- The diagram includes a horizontal axis with points marked O (the object), F1, F2 (focal points), and I (the image).
- A blue vertical line represents the lens.
- Two red lines illustrate the paths of two principal rays.
- One ray originates at O, travels through the lens, and extends to I.
- Another ray travels parallel to the optical axis until it reaches the lens, then refracts through F2, and extends to I.
Which is the correct description for the missing third principal ray?
Select one:
- a. From the tip of the object draw a ray going through F1; as it crosses the lens it emerges going through F2.
- 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. 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.
- 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.
