Question

Q26 The process of population inversion is to increase
the number of atoms in the Select one:​

Answer 1

Answer:

Normally, a system of atoms is in temperature equilibrium and there are always more atoms in low energy states than in higher ones. ... When this distribution is disturbed by pumping energy into the system, a population inversion will take place in which more atoms will exist in the higher energy states than in the lower.

Answer 2

The process of population inversion is to increase the number of atoms in the higher energy state is larger than the lower energy state.

• In physics, population inversion is the shifting of atomic energy levels in a system to allow laser action to occur.
• A system of atoms is normally in thermal equilibrium, with more atoms in low-energy states than in higher-energy states.
• When this distribution is disrupted by injecting energy into the system, a population inversion occurs, with more atoms in higher energy levels than in lower energy states.
