help with chemistry problem please!!!!?
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 700 nm photons. What is the energy gap between the ground state and excited state in the laser material?
