State what is the frequency of light

Reference no: EM13161172

1.A red laser pointer emits light with a wavelength of 660. What is the frequency of this light? 2.What is the energy of one of these photons? 3.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 660nm. photons. What is the energy gap between the ground state and excited state in the laser material?
