Week 12
Read: Measuring astronomical distances (Chap. 22)
Quiz: Monday. Covers both Leavitt and Slipher's work.
Homework exercises: Astronomical distance: stellar parallax (Ex. 22.1), Astronomical distance: apparent magnitude (Ex. 22.2) Due noon Saturday week 12.
Laboratory exercises: This week, we will do a Spectroscopy Lab (Ex. 22.2). After picking out a minimum of five light sources, you should submit a scanned copy of your lab book pages that include a description of what you observed and a sketch of the emission spectrum for each, including the wavelengths of the spectral lines. This will be due noon Monday week 13. Also, submit your weekly planet observation noon Monday week 13.
