Name (Print) __________________________ Lab Section_________ 1. A bare proton has a mass of 1.0073 u; a bare neutron has a mass of 1.0087 u; and a bare electron has mass of 5.5 x 10 -4 u. The element 12 C has a mass of exactly 12.000 u. Write down an expression for the binding energy of 12 C in units of Joules (1 J = 1 kg m 2 s -2 ) 2. Write down an expression for the wavelength (in microns or 10 -6 m) of a photon that would have enough energy to overcome the binding energy of 12 C (from problem 1) and cause the nucleus to break apart? 3. Would the photon in problem 2 be more or less energetic than a typical photon that is visible to the human eye? 4. Why does it get increasingly difficult to use the “parallax method” to measure the distance of stars from the earth as the distance get larger?

Name (Print) __________________________ Lab Section_________ 5. The atom Na has an absorption line at 0.5 µ (or 5 x 10 -7 m). Suppose we observe a Na- like line in the spectrum of a distant star at a wavelength of 0.55 µ . Is the star moving toward or away from the earth? 6.
