light is produced when electrons ?

Question

move from a lower energy level to a higher one

move froma higher energy level to a lower one

this one also stumped us because, the book says both ways.
please help

Answer 1

moving from a higher to a lower energy level releases energy, producing light, but;
it only produces light in the visible light spectrum when it moves down to level n=2. if it ends up at another energy level, the light released will be infared, ultraviolet, etc... depending on where it ends up.

Answer 2

Energy in the form of light is produced when electrons move from higher energy to lower energy. While moving the other way electrons absorb energy.

Answer 3

An electron moving from a higher energy state to a lower one will produce a photon.

Answer 4

Higher to lower, because they have more free energy at the higher level orbit, and so the loss in energy as the electron is captured by a lower energy orbit is emitted as light.
