Voltageis applied to the aluminum core of the drum. Since light renders selenium conductive, current can flow through the photoconductive layer while the drum is being illuminated, and the electrons released by the atoms are quickly replaced by the electrons that form the current flowing through th...
The wavelength of light is determined by the amount of energy released when the electron drops to a lower orbit. The light released is coherent. It is “organized” — each photon moves in step with the others. This means that all of the photons have wave fronts that launch in unison. ...

Photons are released as a result of moving electrons. In an atom, electrons move in orbitals around the nucleus. Electrons in different orbitals have different amounts of energy. Generally speaking, electrons with greater energy move in orbitals farther away from the nucleus. For an electron to ...
Neutrinos are the smallest subatomic particles, i.e. elementary particles with a half-integer spin known as fermions. Like photons, neutrinos have zero electric charges. They are electrically neutral. And, thus the name “neutrinos”. According to the laws of physics, if there is a particle,...
Antimicrobial resistance (AMR) is an urgent public health threat. Advancements in artificial intelligence (AI) and increases in computational power have resulted in the adoption of AI for biological tasks. This review explores the application of AI in ba
Photons, for example -- the smallest measure of light, which have no mass or electrical charge -- can still bounce a particle around, changing its velocity and speed. This is called Heisenberg's Uncertainty Principle. Werner Heisenberg, a German physicist, determined that our observations have ...
A second-order coherent process is employed, up-converting two lower energy photons precisely to twice the incident frequency (half the wavelength) of an excitation laser. This nonlinear imaging technique has proven effective in the specific and sensitive visualization of endogenous extracellular matrix ...
Alternatively, are photons of electromagnetic energy being released by the bond formation, similar to what happens when an electron moves from a higher to a lower orbital? Is there a good source for me to learn more about the physics of chemical reactions?
Light is a form of energy that can be released by an atom. It is made up of many small particle-like packets that have energy and momentum but no mass. These particles, called light photons, are the most basic units of light. (For more information, see How Light Works.) Atoms ...
