Why the spontaneous radiation incoherent?
Because the moment of emission the polarization and the propagation direction , the direction of the wave vector is random. Spontaneous emission causes incoherent radiation.
What is the difference between spontaneous emission and stimulated emission?
stimulated emission causes due to the energy difference between the higher and lower energy level state, but it doesn't depends in the case of spontaneous emission . spontaneous emission causes without any stimulation .In stimulated emission energy transfer is twice the energy transfer of spontaneous emission.
What is the difference between spontaneous and stimulated emission of light?
stimulated emission causes due to the energy difference between the higher and lower energy level state, but it doesn't depends in the case of spontaneous emission . spontaneous emission causes without any stimulation .In stimulated emission energy transfer is twice the energy transfer of spontaneous emission.
Principle of Spontaneous emission and stimulated emission?
How the nucleus emits radiations spontaneously?
Difference between stimulated and spontaneous emission?
emissions is stmulated when a stimulus takes over them. Spontaneous emissions happens when the individual is very sensitive.

How can spontaneous emission be control?
That's why it's called spontaneous emission you cannot control it. But there is a kind of emission which is called stimulated emission emission. People use stimulated emission in lasers and it can be controlled.

What is the difference between spontaneous emission of radiation and stimulated emission of radiation?
The laser causes the stimulated emission of radiation. The light emitted is monochromatic and coherent,that is plane polarised. I imagine that spontaneous emission occurs in a Light emitting diode ,monochromatic but not polarised. Hope this is of help
Spontaneous emission of radiation from an atom?
This physical phenomenon is called radioactivity.
What is the significance of Einstein's A and B coefficients?
Einstein introduces A and B coefficients to describe spontaneous emission and induced absorption and emission.
Difference between stimulated and spontaneous emission?
emissions is stmulated when a stimulus takes over them. Spontaneous emissions happens when the individual is very sensitive.
What are conditions required for laser action?
1. Population inversion should be achieved. 2. Stimulated emission should be predominant over spontaneous emission
What is spontaneous emission of radiation from an element?
This could have many names such as 'decay', 'radioactive decay', or 'radiation.
