Red light has 1.8 eV, and blue light has 3.1eV can these numbers be changed to increase, or decrease.
Electron voltage requirement, in electrons is different in every single atom, and molecule.
The electrons, electron voltage requirment seems fixed, and cannot be changed, unless the electron moves away from the nucleus to a higher shell.
So if lights electron voltage, can be changed to increase, or decrease, transmission should occur in the electron.
Could opaque objects be made translucent.
Its like light is getting transmission, without being absorbed, and you can see through the opaque object.
Electrons absorb 1 photon per 1 electron, so you cannot play around with mixing EM waves.
The electron will choose to absorb 1 photon then ignore the other photon of another EM wave that is not visible light.
There are so many ways to play around with light, slow it down, play around with wavelength, and frequency, there must be a way to do this.
I am grateful for your help, anything helps, even a few words.

Different semiconductors have a different bandgap, which require a different voltage to allow current to flow, and this produces light of different wavelengths.

Just as light production depends on the chemical structure, so light absorption depends on the chemical structure.

Unfortunately, if you are studying chemical structures, and you don't like the fact that they absorb light, the only option is to change the chemical structure, ie it is no longer the thing you were trying to study. :(
