vam Show all your work for the following questions. Make sure to show all the formulas used and have proper significant digits to receive full marks. 1. Explain what absorption and emission lines are and how they are created. How are they related to each other? (4) 2. In a recreation of Thomson's experiment to find the mass of an electron, a cathode ray tube is set up. The electric field of 1.71x10*N/C is between the plates and a magnetic field of 6.85x10AT. These settings result in the electrons traveling straight through when they are both turned on. After shutting down the electric field, the electron is deflected on a circular path with a radius of 0.150m. Determine the charge to mass ratio according to the experiment. (4)
