Why the light emitted in spontaneous emission is poly chromatic whereas the light in stimulated emissions is monochromanti?
If E1 and E2 be two energy level such that E2 >E1, in both emission the energy difference is fixed, so the frequency and so the wavelength thus the light emitted in both case should be monochromatic but why the light emitted in stimulidated emission is alone monochromatic ?
