2 cards from this section. Quick, good the night before a test.
What is refraction?
Think about what happens to light when it enters water.
What does the focal length of a lens determine?
Consider what happens when you change the shape of the lens.
What is the thin lens formula?
Think about how lenses operate when light interacts with them.
True or False: The lens maker's formula is only applicable to concave lenses.
Consider both convex and concave types.
Design a lens system with two lenses to achieve a specific magnification for distant objects. Outline the needed parameters.
Consider the final focal point to achieve the proper image distance.
Given a lens with certain curvature parameters and material, derive the focal length and assess its applicability in real-world systems.
Check how varying materials change the refractive index.
