Photons are only visible when electrons travel from the ground state to the excited state. True
False

False

Explanation:

When an atoms of an element is energized, some of the electrons will absorb the energy an move to a higher level or excited state for a short time period after which it will move back to the ground state or intermediate energy state

When the electron moves from the higher energy or excited state to a lower energy state, the energy it initially absorbed to raise its energy state is given off as photon which is seen as a visible light when such electrons fall from level 3 to level 2.

thats how its supposed to be

i think that the answer is c
