1. Using the figure below, calculate the wavelength (in nm) and the frequency (in Hz) of the electromagnetic radiation with an energy equal to 1.81 x 10-23 J/photon. Based on your answers, circle the type of radiation this energy corresponds to.

When a hydrogen atom is excited it emits light of a certain color when the electron falls from the n = 5 to the n = 2 energy level. Calculate the wavelength in nanometers of this light and determine what color would be seen when this occurs. Use the information on the attachment to determine the color.
