Unformatted text preview: 1 C Radius of Curvature at 10 cm, 3 cm object is at 15 cm. Find graphical solution. Calculate the analytical solution on the bottom of the page. [10 pts each Ray (up to 4), and 20 pts for analytical solution, 40 pts for signing your name] f Physics 208N-004 Lecture #30 – 4 April 2011 Chapter 33: 1-3 Lenses and Optical Instruments • Thin Lenses; Ray Tracing • The Thin Lens Equation; Magnification • Combinations of Lenses • Lensmaker’s Equation • Cameras: Film and Digital • The Human Eye; Corrective Lenses • Magnifying Glass • Telescopes • Compound Microscope • Aberrations of Lenses and Mirrors 2 Thin lenses are those whose thickness is small compared to their radius of curvature. They may be either converging (a) or diverging (b). 33-1 Thin Lenses; Ray Tracing Parallel rays are brought to a focus by a converging lens (one that is thicker in the center than it is at the edge). 33-1 Thin Lenses; Ray Tracing 3 A diverging lens (thicker at the edge than in the center) makes parallel light diverge; the focal point is that point where the diverging rays would converge if projected back....
