My name is Nicholas Lee, and I am studying neuroscience, and I am trying to find a way to find better ways in neuroimaging, and microscopy to see the brain better, to find better cure for Parkinson's disease, and Alzheimer's, and epilepsy If you have a four inch cubic block of glass, and carbon, light passes through the glass no problem, but the carbon will absorb some red, yellow, green, and blue light, but if you look at the carbon absorption for light, not all blue, green, yellow, and red light get absorbed by carbon, like in the diagram below.

Some materials have larger band gaps than others, glass is one of those materials, which means its electrons require much more energy before they can skip from one energy band to another, and back again.
glass cannot absorb high wavelengths of light, but the glass will absorb ultraviolet waves, which have a smaller wavelength.
So if the two four inch cubic block of glass, and carbon, are placed in a dark room with no light hitting the blocks at all, and you just shined the colors of light at the carbon, that did not excite the electrons to a higher shell energy level, what would happen.
Question 1. Does the light from the blue, green, yellow, and red pass through the carbon block, but I think you would just see the block of carbon just be black right, even though certain colors of light are passing through it, is this correct.
All light colors pass through the glass no problem, so for the carbon things are different, the amorphous material the glass is made from is not necessarily what is making the glass transparent, its the energy of the electrons in the glass that cannot get exited for the light, so the light gets transmitted through the block of glass.
So for the carbon, does its electrons either absorb more energy, or because it has 2 electrons in shell 1, and 4 electrons in shell two, silicone which is mostly what glass is made from has two electrons in shell 1,and 8 in shell 2, and 4 in shell 3.
So it cannot be the amount of electrons I think just the energy of electrons, but can you explain why the energy levels are different for some electrons.
Here are a list of some ways to effect electron:
1. Cold temperature, can this effect the way electron absorb photons of light.
2. Certain wavelengths of light
3. Amorphous material.
4. energy of electrons, some wavelengths of light to not get absorbed by some electrons.
Do you know of any other ways the electron can not get excited.
Thank you for your help, anything helps, even a few words.
