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?
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 4.86 mL of a 0.196 napthalene solution is irradiated with 270 nm light and 8.13e-21 J of energy are emitted, what percentage of the napthalene molecules emitted a photon?
What is the frequency of a light wave with a wavelength of 560 nm? What is the energy of a photon with a wavelength of 560 nm?
