Chapter 30 Objectives:
When you have completed chapter 30, you should be able to:
- ... distinguish between converging and diverging lens by their
shape.
- ... locate images formed by converging and diverging lenses
using ray diagrams or lens equations, and identify the image as
real or virtual.
- ... describe the operation of simple optical instruments such
as a camera, projector, magnifying glass, refracting telescope,
binoculars, and compound microscope.
- ...describe the normal optics of the human eye.
- ...explain the causes of nearsightedness and farsightness in
terms of the optics of the eye, and explain how a lens is used to
correct these conditions.
- ...describe common lens defects, such as spherical and
chromatic aberration.
- ...describe the optics of a pinhole lens.
