Answer: atoms and elements?) ... A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing just one proton and one electron.

Do quasars reside within or without side of galaxies?
sveticcg [70]

They almost entirely reside within galaxies because quasars are a subset of blackholes with a large and fast enough accretion disk to generate a beam of interstellar material perpendicular to itself. This typically only occurs in the largest black holes at the center of galaxies (supermassive blackholes) or at least stellar black holes---which still occur within galaxies because the material is necessary to form them.

Consider light energy that is momentarily absorbed in glass and then re-emitted. Compared to the absorbed light, the frequency o
fredd [130]

The frequency of the re-emitted light is identical to that of the absorbed light.

To find the answer, we need to know more about the frequency of light.

<h3> Why the re-emitted light has the same frequency?</h3>
  • The wavelength of the light that is momentarily absorbed in glass and then re-emitted is the same, which explains why the re-emitted light has the same frequency as the absorbed light and the frequency of the absorbed light is the same.
  • An electromagnetic wave's energy is inversely related to its frequency.
  • The relationship between the wave's wavelength and frequency depends on the speed of light:

                              frequency=\frac{c}{wave length} , c is the speed of light.

  • Despite not having mass, light still has energy, and that energy is conserved.
  • As a result, in order for there to be energy conservation, the energy of the light that is received and reemitted must be equal.

Thus, we can conclude that, the re-emitted light's frequency matches the absorbed light's frequency.
