An excited hydrogen atom has its electron in the third energy level (n = 3). The electron relaxes (falls down) to the second energy level (n = 2) and emits a photon of light in the process. Calculate the energy, frequency, wavelength, and determine the color of light emitted from an excited hydrogen atom.
