To \"jump\" to its first excited state, an electron must: (choose all correct) N

Question

To "jump" to its first excited state, an electron must: (choose all correct)

Note: this applies to ordinary levels of light intensity, not intense laser beams!

A.absorb exactly one photon

B.absorb two or more photons

C.absorb photons with energy that matches the difference in energy of ground and excited states

D.absorb photons with much more energy than the difference in energy of ground and excited states

E.absorb half a photon having twice as much as the energy difference between ground and excited state

Explanation / Answer

to go to exicted state from ground state electron must absorb the energy required to reach exicted state which is equal to difference between energy of ground state and exicted state.

answer = option C = absorb photons with energy that matches the difference in energy of ground and excited states
