Unformatted text preview: Problem 2: Make a graph of the magnitude difference M b -M v for a black body as a function of temperature for the temperature range 3,000-30,000K. To simplify the calculation, you may assume that magnitudes are determined in a narrow range of wavelengths around the peak of each filter. Problem 3: For a 300K blackbody, over what range of wavelengths would you expect the Rayleigh Jeans law to be a good approximation? Problem 4: Calculate the energy per squared centimeter per second reaching Earth from the Sun. Problem 5: How does the absolute magnitude of a star vary with the size of the star (assuming the temperature stays constant)? Problem 6: If we double the temperature of a blackbody, by how much must we decrease the surface area to keep the luminosity constant?...
