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?
Nitrogen:Nitrogen emits blue (multiple wavelengths) and red light. Other Gases:Other gases in the atmosphere become excited and emit light, although the wavelengths may be outside of the range of human vision or else too faint to see.Hydrogenandhelium, for example, emit blue and purple. Altho...
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?
A U.S. lab has successfully sparked a fusion reaction that released more energy than went into it. But there’s still a long way to go toward fusion as a clean energy source.
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,...
Another type of diffuse nebula, a reflection nebula doesn’t emit its own light, but scatters light from embedded stars. (Image credit: NASA, JPL-Caltech, Kate Su (Steward Obs, U. Arizona) et al.) Planetary nebula: The Helix Nebula This is composed of expanding gas that was blown off...
In a bomb that is working properly, more than one neutron ejected from each fission causes another fission to occur. It helps to think of a big circle of marbles as the protons and neutrons of an atom. If you shoot one marble — a single neutron — into the middle of the big circle...
The gas in the tube is ionized by a strong electric field which generates light by exciting the electrons in the CO2 molecules to a higher energy state, thereby generating a photon. When a photon passes near an atom in the excited state it causes that atom to release a photon. These ...
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 ...
