The light intensity decreases __________ with distance in the medium

An electron in ground state is

The passing of an electron from one energy level to another within the atom is called

The number of atoms per unit volume that occupy a given energy state is called

Interaction with light photons is one of the means of supplying energy to electron to undergo transition

The atoms _______ energy to raise from a lower energy level to upper energy level

The type of emission of light on its own is called

The process where atoms absorbs the photons incident in the medium and go into the excited state is called

The process of Stimulated emission causes

The process responsible for laser action

The rate of absorption transition R_abs depends on

The rate of spontaneous emission R_sp depends only on

The rate of stimulated emission R_st depends only on ρ(ν)

This is NOT a feature of spontaneous emission

Find the feature of stimulated emission

The net intensity of light due to spontaneous emission is I_total = NI
