Before an atom emit a light, it must absorb
energy, it electron must be excited, the excited electron will jump from its
ground state to a higher energy level only when the energy absorb is more than
the energy of that state,
electron that jump to the higher energy level
will return to the ground state after it has released the extra energy,
this is state in Bohr 2nd atomic
postulate, “ atoms only emits energy when its electron jump back to its ground
state.
