1. Explain how the wavelength, frequency and energy of a wave are related. Connect these concepts to the mathematical equation relating them. 2. Calculate the energy of the violet light emitted by a hydrogen atom with a wavelength of 410.1 nm. 3. An electron in the n = 7 level of the hydrogen atom relaxes to a lower energy level, emitting light of 397 nm. What is the value of n for the level to which the electron relaxed?
