Question
An object is placed between two lenses. The surrounding medium is air, as usual. The squares on the grid measure 6.0 cm x 6.0 cm. F1 is a focal point for Lens 1; F2 is a focal point for Lens 2
PROBLEM 5 (continued from the previous page)
(f) [1 point] Does each lens also create a second image, using the image created by the other lens as a second object?
[ ] Yes, both lenses create a second image [ ] Only Lens 1 creates a second image
[ ] No, neither lens creates a second image [ ] Only Lens 2 creates a second image
(g) [1 point] Based on the typical ray diagrams we have done in this course, what is wrong with the ray diagram above?
[ ] We would expect the two rays to change direction so that they both pass through the focal point on the right of the lens.
[ ] We would expect the two rays to change direction so that they both appear to diverge away from the focal point on the left of the lens.
[ ] We would expect that, on the right of the lens, the two rays would meet at the location of the tip of the real image of the object.
[ ] We would expect the ray that is parallel to the principal axis to change direction to pass through the focal point on the right of the lens.
(h) [1 point] Could the ray diagram above actually be correct, in a somewhat unusual situation?
[ ] Absolutely not
[ ] Yes, such as if the system was immersed in a fluid that had an index of refraction more than the index of refraction of the lens.
[ ] Yes, such as if the system was immersed in a fluid that had an index of refraction equal to the index of refraction of the lens.
[ ] Yes, such as if the system was immersed in a fluid that had an index of refraction less than the index of refraction of the lens.
