Hi, my name is David. I'm a High School student in Virginia. I'm doing a research project that concerns controling the frequency and wavelength or energy of a photon that is "absorbed" and emitted by an electron. Here are some assumptions and questions I am working on. Any help would be greatly appreciated:
1. If two 3.5 n photons are "absorbed" by an electron cloud, one 4n photon can be emitted.
2. Supposedly when light hits matter, it asorbs the colors you don't see visually and "reflects" the colors you do see. Is this true or is it that the electrons absorb only certain colors/wavelength/frequencies or light and then emit those same colors and THOSE are the colors you see?
3. Why does an electron only absorb certain wavelengths and photons and emit only certain wavelengths and photons (i.e. the same photon it absorbed)?
4. How is the frequency needed to excite an electron determined? In other words why does a certain atom need x amount of energy for an electron to jump to the next level and not less or greater than x?
5. When an electron cloud is polarized it resonates with the frequency of the photon that was absorbed by it. This resonation in turn interacts with the electrons electromagnetic field to emit the same frequency as was absorbed by the electron. So does the electrons electromagentic field in the end determine what frequency and thus color of light/photon is emitted from the atom?
6. If this is true, would it be possible to change, with some kind of outside, controlable force, the electron's electromagnetic field and thus the way it is polarized by light or vice versa? This could in turn control the color of light that is emitted from the electron, making it different than what was absorbed (i.e. white light).
I love science, in particular physics, but I have not had any advanced courses in it. If there is any major problems with my reasoning, please do not hesitate to tell me. I joined this forum to learn of these problems, and to see if my research project is realistic and possible. I think i understand these concepts, but there is a very good chance I'm wrong. Please post some replies to help me. Thanks.
