Week 12 (Nov. 10, 12, 14)
Read: Measuring astronomical distances (Chap. 22)
Quiz: Monday.
Homework exercises: Astronomical distance: stellar parallax (Ex. 22.1), Astronomical distance: apparent magnitude (Ex. 22.2)
Laboratory exercises: In the next two weeks, we will do telescopic observations of Saturn. Each group must sign up for one Monday evening observation session in which you will carry out the planetary observations (Ex. 19.2). When you have done so, you must submit a scan of your lab book including the time, date, and location of your observations, the planet that you observed, and an explanation of how you calculated the angular width of the planet by turning off the scope motor.
During the evening lab session that you are -not- doing telescopic observations, you should do the Spectroscopy Lab (Ex. 22.2). After picking out and observing 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.
