Question

In led which type of emission will occur spontaneous or stimulated emission

Answer 1

Answer:

Spontaneous emission of radiation happens spontaneously (who would have thought!); the light is emitted randomly without any connection to any of the other emitted photons. In stimulated emission, one photon "causes" another photon just like it to be emitted by an atom. The book describes this as making a "perfect copy" of the first photon.

Spontaneous emission of radiation is unpredictable and independent. Stimulated emission of radiation occurs when an excited atom duplicates a passing photon. The photon that is emitted is exactly like the stimulated photon.
