Typical Conceptual Questions for Physics I - Light and Quantum
This is a stellar overview of everything light and quantum! There are 30 multiple choice questions, none of them requiring any mathematical computation. There are a few diagrams to analyze: light rays striking reflective and refractive...

Georgia State University: Hyper Physics: Thin Lens Equation
This is an informative site from Georgia State University. It gives a discussion of the thin lens equation and an illustration of its use in determining the image distance based upon the object distance and the focal length.
Physics Classroom
The Physics Classroom: Image Formation by Lenses
This lesson explains what lenses are, the different between a converging and diverging lens, the difference between a double convex and double concave lens, and gives definitions for terms related to lenses.
CK-12 Foundation
Ck 12: Concave and Convex Lenses
[Free Registration/Login may be required to access all resource tools.] Students describe and predict image formation as a consequence of refraction through a thin convex lens.
Physics Classroom
The Physics Classroom: Refraction/ray Model of Light: Image Formation Revisited
Students take an in-depth look at the physics behind image formation.
Khan Academy
Khan Academy: Thin Lens Sign Conventions
Have you ever wondered why some people need glasses and others don't? It's because of the way light is focused by the lens in your eye. This lens, like magnifying glasses, eyeglasses, and contact lenses, is considered a thin lens.
