(a) A green laser pointer emits light with a wavelength of532 nm. What is the frequency of this light? (b) What isthe energy of one of these photons? (c) The laser pointeremits light because electrons in the material are excited (bya battery) from their ground state to an upper excited state.When the electrons return to the ground state, they lose theexcess energy in the form of 532-nm photons. What is theenergy gap between the ground state and excited state in thelaser material?

Question
(a) A green laser pointer emits light with a wavelength of
532 nm. What is the
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?
