when some energy is suplied to an electron in a higher energy level E2 then how come it drops down to a lower energy level E1 but as per our knowlwdge of physics...it should jump to a higher energy level E3.
An energy level jump refers to the movement of an electron from one energy level to another within an atom or molecule. This can occur spontaneously or be induced by external energy sources.
Stimulated emission is a process in which an excited atom or molecule emits a photon of light upon interaction with another photon of the same energy. This occurs in lasers and other light-emitting devices.
When an excited atom or molecule undergoes stimulated emission, it releases a photon and returns to a lower energy state. This can result in an energy level jump as the electron moves to a lower energy level.
Energy level jumps in stimulated emission play a crucial role in the functioning of lasers and other light-emitting devices. They allow for the controlled release of photons, resulting in coherent and amplified light output.
In spontaneous emission, an excited atom or molecule releases a photon of light without any external influence. In stimulated emission, the photon is released due to the interaction with another photon, resulting in a more controlled and amplified process.
