Chapter 34: Reflection, Refraction, and Optics

Study Plan

The Hubble Space Telescope uses a large concave mirror, with a radius of curvature of 11 m, to image distant galaxies.

With the laws of geometric optics presented in this chapter, we can answer a variety of questions about images formed by the mirror:

  • How far from the mirror does the image of a distant galaxy form? (Example 7, page 1129)
  • A technician is 4.0 m from the mirror. Where is his image? (Example 10, page 1134)
  • The image of the technician is large and upright. How do we calculate such image properties? (Example 13, page 1140)
  • How do we measure the magnification of a telescope? (Example 16, page 1151)

Organize

  1. Prepare for lecture by reading the assigned sections from Chapter 34 in your textbook or ebook. This will provide an organizing framework for concepts introduced in lecture, and help you take better notes.
  2. Take the checkup quiz and work the Checkup questions in your textbook to assess your understanding of basic concepts. Take note of any topics you need to review further.
  3. Review the Examples from your textbook. These progress from simple to complex, and provide concrete illustrations of the concepts discussed.
  4. Review the Problem Solving Techniques boxes on Sign Convenstions for Mirrors (page 1132), Images of Spherical Mirrors (page 1134), Sign Convenstions for Lenses (page 1138), and on Images of Lenses (page 1143) from your textbook.

Learn

  1. Re-read Chapter 34 and review your lecture notes.
  2. Access the Online Concept Tutorials given for this chapter. Tutorials use animation and interactive exercises to help develop your understanding of fundamental topics.
