I have a big doubt.
I have found an answer of other community a question about a relation between wavelength and transmit power.
My doubt is according to the reply
If you have a low wavelength and more beam power you need less photons per mW, for high wavelength and low beam power there are more photons per mW.
As I understand, Photon energy is inversely proportional to wavelength. If we have a low wavelength, we will have high photon energy. If we have a high wavelength, wewill have low photon energy, right?
