What is the basic difference between

$2$

stimulated emission and spentrmecousemission?

$2$

Explain that:$-$ the number of photons released depends on the number of electrons in the upper Lavel.

Explain: What happens to the released photon that Collides with atoms, molecules or walls?

What does non$-$radiative decay depend on$?$

When does stimulatedemission dominate spontameous emission?

$P_{17}c{h}_1$:$Q$ which of these two processes will dominate for ordinary thermal sources of light?
