1. Presume that you have not done the calculations to convert wavelength to energy yet. Only having the wavelengths of each emission line available to you, could you still answer question number 1 (without actually doing the conversion)? Explain why or why not?
2. If the 3 → 1 transition has an energy of 1.94 x 10-18 J, what do you think the energy of the 1 → 3 transition is? Explain why.

To understand electromagnetic radiation and be able to perform
calculations involving wavelength, frequency, and energy.
Several properties are used to define waves. Every wave has a
wavelength, which is the distance from peak to peak or
trough to trough. Wavelength, typically given the symbol λ
(lowercase Greek "lambda"), is usually measured in meters. Every
wave also has a frequency, which is the number of
wavelengths that pass a certain point during a given period of
time. Frequency, given the symbol...
