Question

The number of atoms in the excited state become much greater than the number of atoms in the ground state this known as

Answer 1

Answer:

In science, specifically statistical mechanics, a population inversion occurs while a system (such as a group of atoms or molecules) exists in a state in which more members of the system are in higher, excited states than in lower, unexcited energy states

Explanation:

It is called an "inversion" because in many familiar and commonly encountered physical systems, this is not possible. This concept is of fundamental importance in laser science because the production of a population inversion is a necessary step in the workings of a standard laser.

Answer 2

The number of atoms in the excited state becomes much greater than the number of atoms in the ground state is known as population inversion.

• The term population inversion describes an assembly of atoms in which the majority are in energy levels above the ground state; normally the ground state is occupied to the greatest extent.
• A population inversion occurs while a system (such as a group of atoms or molecules) exists in a state in which more members of the system are in higher, excited states than in lower, unexcited energy states.
• It is called an "inversion" because, in many familiar and commonly encountered physical systems, this is not possible.
• This concept is of fundamental importance in laser science because the production of a population inversion is a necessary step in the workings of a standard laser.
