Fluorescence is a process where a molecule absorbs a photon and then emits a photon of lower energy. Napthalene absorbs photons with a wavelength of 270 nm and emits a photon with a wavelength of 349 nm. If 4.02 mL of a 0.124 napthalene solution is irradiated with 270 nm light and 2820 J of energy are emitted, what percentage of the napthalene molecules emitted a photon?

(a) A green laser pointer emits light with a wavelength of
532 nm. What is the frequency of this light? (b) What is the energy of one of these photons? (c) The laser pointer emits light because electrons in the material are excited (by a battery) from their ground state to an upper excited state. When the electrons return to the ground state, they lose the excess energy in the form of 532-nm photons. What is the energy gap between the ground state and excited state in the laser material?

c) The energy gap between ground state and excited state corresponds to the energy of the light emitted. As wavelength of emitted photons is 532 nm, energy gap is:
