Simple Lens Handout
- Find and read three different discussions of simple lenses on the InfoMall:
one conceptual
one intermediate
one advanced
Copy and paste a portion of each one, with its citation, into your document.
- Solve [i.e., given an object distance and the focal length, compute the image distance,
magnification and state if the image is "real" or "virtual"] two simple lens numerical
problems using the thin lens formula:
a)one for a convex lens - do three different cases; i>2f; 2f>i>f; i<f
b) one for a concave lens. Why is only one necessary for a concave lens?
{Hint:You may make up your own given lens values or find appropriate numerical
problems on the InfoMall}
Show each solution with a ray diagram.
- How does the image formation of curved mirrors compare to that of simple lenses.
