Question

If you decrease the wavelength of a photon's path from a laser does that in turn decrease the amount of photons emitted by the system if the energy level stays constant? For example, going from a red colored laser to a blue color. That decreases the wavelength which in turn increases the amount of energy per photon. Dividing total energy by the energy per photon gives you the number of photons. This should be a smaller number due to the two inverse proportions.

Answer 1

Yes. Since you're going from red to blue light, each photon has more energy. Since you're specifying that the energy has to remain constant, then it takes fewer blue photons to match the amount of energy we had with red ones.

Answer 2

Thanks!
