Question

the distribution ratio of excited atoms to group state atoms in few depend upon......​

Answer 1

Answer:

because the production of a population inversion is a necessary step in the workings of a standard laser.

Answer 2

number of state

The squared length of the orbital is directly related to the number of states to the fourth power. When atoms are in the excited singlet state, spontaneously breakdown processes will occur to the ground state happening at a rate proportionate to their number. The atom emits a photon as a result of the energy differences between two states of energy.
