Document Summary
The difference in internal energy of the atom (upper+lower orbit) is equal to the energy of the photon created. This photon has a speci c wavelength hence colour. Luminescent emission > source of energy required to be absorbed by atoms, so the electrons can jump to higher energy levels. Breaks a glass vial + allows 2 chemicals to come into contact + react. 2 chemicals that react + release energy. Inside the vial there is hydrogen peroxide (h2o2) Outside vial there is phenyl oxalate ester. Also outside the vial there is a uorescent dye. Chemical reaction is exothermic meaning it creates energy. That energy is observed by uorescent molecule. Allows the electrons to jump to higher levels. When the electrons drop to lower levels , it releases photons + generates light. Emission of light from an organism that functions for the organisms survival including. Uses of bioluminescence: attracting prey, startling predators, camou age, attracting mates, self defence.
