Introduction: Along with mirrors, lens complete the set of simple optical elements. Lens yw2^kk93|
have been used for hundreds of years. Galileo constructed the first telescope from a pair of lens eZ

in 1609 and used it to discover, among other things, several of Jupiter’s moons. A lens forms 9. Q;J#;1
images by bending the incoming light as it passes. Image formation can be understood by .OVI Qxf
treating the incoming light as rays and using a simple geometric arguments. Like much of basic W~

physics, this approach isn’t completely correct but is a good approximation. Because of the Sb+pB58&N
geometric nature of the approximation, one can analyze a lens with geometry. This sort of ~oh=QakW
approach is called ray tracing. In today’s lab, we will form images with lens and analyze the JNRG [j
system with ray tracings and with equations.
