There are many different ways to produce photons, but all of them use the same mechanism inside an atom to do it. This mechanism involves the energizing of electrons orbiting each atom's nucleus. How Nuclear Radiation Works describes protons, neutrons and electrons in some detail. For example,...
What causes the emission of radiant energy? What is the path electricity takes called? What carries the energy in electromagnetic radiation? What part of an atom produces a magnetic field? What does solar energy mean? What produces electromagnetic radiation?
Each free electron in the n-type region originates from a neutral donor atom. Likewise, as a hole moves from the p-type to the n-type region, it leaves behind a negative acceptor ion in the p-type region. Since each hole is contributed by one acceptor atom in p-type region. Both ...
Free Mang-writing in the universe is an infinite extension of life in the universe. No matter where in the universe, no matter when in the universe, Mang-writing is everywhere. The particle is Mang-writing, the universe is Mang-writing, the atom is Mang-writing, the energy is Mang-writin...
What causes the refraction of light? What kind of energy is stored energy? Which electromagnetic waves emitted from the sun produce heat? What kind of energy does an unlit match have? What is the source of all energy in the atmosphere?
energy released as light produces the aurora. Each element releases specific wavelengths, so the colors you see depend on the type of atom that is excited, how much energy it received, and how the wavelengths of light blend with each other. Scattered light from the sun and moon may affect ...
When a photon passes near an atom in the excited state it causes that atom to release a photon. These photons then bounce off the two mirrors until there are enough collected photons to pass through the semi-reflective mirror. The temperature in the tube must be kept low for optimal ...
Holes are formedwhen electrons in atoms move out of the valence band(the outermost shell of the atom that is completely filled with electrons) into the conduction band (the area in an atom where electrons can escape easily), which happens everywhere in a semiconductor. ...
Two atoms of hydrogen are combined to create helium-4 and energy in several steps: Two protons combine to form a deuterium atom (hydrogen atom with one neutron and one proton), a positron (similar to an electron, but with a positive charge) and a neutrino. A proton and a deuterium atom...
In current electricity, electric charge is carried by electrons and protons within an atom. Protons have positive (+) charge, while electrons (-) have negative charge. Since it is an electric charge in motion, form a sudden discharge such as a lightning bolt or a spark between your finger ...
