In this speed of a galaxy learning exercise, students use a given equation for the speed of an object and they use the spectral lines for Hydrogen Alpha and Beta from the Seyfert galaxy to answer 6 questions. They determine the observed wavelengths, the rest wavelengths, the velocities of the wavelengths and if the galaxy is moving towards or away from the Milky Way Galaxy.
