Key Ideas by Lecture

This is a summary of some of the main ideas. The links point to sites that might be of interest: some are more detailed explanation of what we did in lecture, others are more advanced material than we'll cover in lecture

  • Reflection and Refraction (Giancoli Ch. 33)
    geometric optics approximation
    speed of light in different media
    reflection angle equals incidence angle
    mirrors: flat, curved
    mirror equation, defintions and sign conventions
    refraction: snell's law
    total internal reflection

  • Lenses and Optical instruments (Giancoli Ch. 34)
    Thin lens approximation
    Types of lenses
    lens equation and sign conventions
    multiple lenses
    lensmaker's equation

    • Imaging with lenses page, Mount Holyoke (has applet)
    • Diverging lens applet, Web Physics at Mississippi State U.
    • Geometrical Ray Tracing, FSU
    • Matrix methods for multiple lenses (we won't cover this in lecture but if you want to follow up this is one place to start!) Refraction/reflection through a boundary(lens or mirror) and propagation through space to the next boundary (lens or mirror) can be calculated using products of matrices acting on a vector describing the initial ray. See also lecture notes here, for example, second and third lectures
    • How a pinhole camera works from (caveat, this pops up lots of ads!)
    • List of large astronomy optical telescopes by SEDS and Telescope information by N. Strobel
    • Lensing by spacetime (gravitational lensing) and the analogy with optics we covered is described here. A striking example is here, of a galaxy cluster lensing things behind it.
    • also see above links as many discussions consider lenses and mirrors together
    • X-Ray telescopes compared to optical (light) telescopes
