2. Describe the solar interior, including the main physical processes that occur at different depths within the sun.
3. With the mass and size of the sun, calculate the sun's mean density. Compare this with the mean densities of the outer planets.
4. Calculate the wavelength bands at which the photosphere, chromosphere, and the corona emit the most radiation. Explain how your results suggest the best way to observe these regions in the solar atmosphere.
5. If a star has an apparent magnitude of -0.4, and a parallax of 0.3", what is (a) its distance? (b) its absolute magnitude?
