which of the following statements is true about energy quantization at the atomic level?

the energy of a photon depends on the frequency of the emission.
the energy of a photon depends on the mass of the neutrons and protons.
an electron can only move from a lower energy level to a higher energy level.
an electron may emit or absorb a quarter of a photon during energy level transitions.

The energy of a photon depends on the frequency of the emission.

Explanation:

E = hν  

where E is the energy of a photon, ν   is the frequency of photon and h is Planck’s constant.  

Energy of a photon is quantized and is directly proportional to the frequency of the emission.  

Quantized energy of a photon explained the photoelectric effect. It was proven that light not has wave nature but particle nature as well. This later gave rise to wave particle duality of light waves.

The energy of a photon depends on the frequency of the emission.

Explanation:

Just took the test, good luck to anyone taking it.

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

i think the answer is terrae but not 100 percent sure. ▓▬▬ §
