The energy levels of a particular quantum object are −8.2 ev, −4.4 ev, and −1.8 ev. if a collection of these objects is bombarded by an electron beam so that there are some objects in each excited state, what are the energies of the photons that will be emitted?
1. 12.6 ev, 2.6 ev, 10 ev
2. 3.8 ev, 12.6 ev, 2.6 ev
3. −8.2 ev, −4.4 ev, −1.8 ev
4. 3.8 ev, 6.4 ev, 2.6 ev
5. 8.2 ev, −4.4 ev, −1.8 ev
6. −3.8 ev, −6.4 ev, −2.6 ev
7. 6.4 ev, −4.4 ev, 1.8 ev
8. 3.8 ev, 6.2 ev, 12.6 ev
9. 10 ev, −3.8 ev, 6.4 ev
10. 12.6 ev, 10 ev, 6.2 ev

4. 3.8 eV, 6.4 eV, 2.6 eV

Explanation:

Energy levels

= -8.2 ev

= -4.4 ev

= -1.8 ev

The difference in energy levels is given by

Therefore, the energies of the photons that will be emitted are

4. 3.8 eV, 6.4 eV, 2.6 eV

a) cold, dry

explanation:

continental polar masses are cold and dry air masses because the cold air cannot hold much moisture. as they move into warmer air, they can trigger precipitation.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
