(0.7 pts) Find the frequency and energy of a photon of light having wavelength of 950 nm. What is the name given to this region of the electromagnetic spectrum ? frequency, ν = energy = name of region: 2. (1 pts) An electron on a hydrogen atom experiences a transition from the 2 nd level (n=2 to the 6 th level (n=6). What is the energy of this transition, and is the photon involved being absorbed or emitted? E = (circle one): absorbed emitted 3.
