- definition - What are coherent and incoherent radiation? - Physics . . .
7 What are coherent and incoherent radiation? I am a mathematician who is self-learning physics In reading Jackson's electrodynamics and other books, I often hear that radiation is incoherent or coherent What does this mean? Does it just mean that the phases are the same in coherent radiation and are different in incoherent radiation?
- What does Coherent mean in coherent spectroscopy?
0 I find this on wiki: "Coherent or resonance spectroscopy are techniques where the radiative energy couples two quantum states of the material in a coherent interaction that is sustained by the radiating field " It gives some insigts but can anyone give a more detailed argument? Thanks!
- Coherent vs In Phase vs Polarized Light - Physics Stack Exchange
What are the distinct differences, if any, between Coherent Light, Light that is In Phase, and Polarized Light? Also: I have found conflicting definitions of coherent light, where one definition is "
- Are two waves being in phase the same as saying that the two waves are . . .
But more general if the phase difference of two waves remains the same during a time that is called "Coherence time", the fields are coherent during that time In reality the fields do not remain coherent for infinite interval and after the coherence time the phase difference drifts
- What exactly is the coherence between waves?
Naively, that means that two waves are coherent if and only if they have the same frequency, which makes the idea of coherence sound silly However, it actually stands in for a lot of real world effects that can destroy interference For example: Light from a fluorescent bulb, which has (roughly) a single frequency, is not coherent
- What does coherent evolution of an $N$-body quantum system mean?
In classical physics we know of coherence of waves and in quantum physics we identify coherent states While those are clearly defined concepts terms, in literature we regularly encouter also that
- What does it mean for a light to have low-coherence?
There are two aspects of coherence: temporal snd spatial If light is temporally coherent, it has a very narrow frequency bandwidth If light is spatially coherent, the source is physically very small In an interferometer using light of high temporal coherence and high spatial coherence, interference fringes can form even if the two beams in the interferometer travel paths of substantially
