Energy is absorbed in discrete amounts.

Calculate the wavelength of radiation absorbed during the ionization of an electron from the n = 1 energy level of hydrogen. (Hint: on the Energy Levels For Hydrogen chart, how much energy is required to ionixe an n = 1 electron?)

If the wavelength of radiation absorbed during the ionization of an electron from the n = 1 energy level of hydrogen is not within the range of visible light, within what range of electromagnetic wave does this wavelength fall?

The Energy Levels for Hydrogen chart shows more transitions than are represented by hydrogen’s emission spectrum because hydrogen’s emission spectrum shows only[removed] lines.
