Do electrons emit light when they jump from lower to higher energy level, or drop from higher to lower?

Question

Do electrons emit light when they jump from lower to higher energy level, or drop from higher to lower?

Answer 1

Dropping from higher to lower.



The other direction would require energy--absorb light.

Answer 2

they emit light when the drop from a higher to lower energy level, according to Bohr's model

Answer 3

Yes the electron emits light when it goes from higher energy to lower energy level.When electron gets energy more than hv then it goes from valance band to conduction band and when it loses energy and have energy less than hv then it comes down from conduction band to valance band.In this time electron emits light as energy because it has to make its energy lower .

Answer 4

If there is a negative charge on the atom carrying the electrons they emit heat. It is rare by nature but they do emit life in manipulated circumstances.

Answer 5

the emit E.M. radiation of wavelength of light when they drop from higher to lower level. it also depends on from which level is the transition made and to which level.

Answer 6

doesn't become a photon. The electron continues to be an electron after it supplies start to the photon. The photon power replaced into the added power that the electron had in its intense power state. by skill of sloughing off that photon, the electron in basic terms returns to its time-honored, decrease power state. The electron's power incorporates 2 elements: the mass equivalent power (e = mc^2) and the kinetic power it has. that is the kinetic power that decreases even as the photon is born; the mass equivalent power continues to be a similar. it truly is, that is nonetheless the straightforward electron yet with a lot less kinetic power after the photon, it really is all kinetic power, is sloughed off.
