QFT view of lower light speed of light in medium [duplicate]
In classical EM theory, if we have a medium whose dielectric coefficient is independent of wavelengths (suppose we filter the incoming signal to a certain frequency band), then the waveform gets to ...

On the level of Newton's particle theory of light
Huygens and Maxwell have wave theories about light.
On the other hand Planck and Einstein have theories about particle nature of light and could explain blackbody radiation and photoelectric effect ...

Is interference of light a quantum phenomenon?
I am wondering whether the light interference is a quantum phenomenon. Or, alternatively, is there any interference in Maxwell's theory understood as a classical field theory?
The reason I am puzzled ...

How to interpret light and photon?
I've been trying to solidify my understanding on properties of light and this is what my understanding is so far:
Light is an EM wave that travels in a constant speed C.
Light has a quantized energy ...

Can Two Electromagnetic waves cancel each other if it 180 degree phase moving in same direction?
If we can send two electromagnetic waves -180 degree out of phase- in same direction, then the interaction of this wave with air molecules will be less due to the low intensity of the combination. So,...

Is reflection and refraction the same thing - bouncing of light?
I've been trying to wrap my head around what determines whether a ray of light is being reflected or refracted. A beam of light does both, as shown in this picture.

Gives light reflected on glass the only sine-waves?
If you put a light beam on glass some of the photons are reflected but the most of them will pass through the glass. Depending on the thickness of the glass light will be reflected from 0% till 16% ...

Validity of the 'photon wavetrain' model of coherence
In some optics textbooks, coherence is introduced with the "photon wavetrain" model. In this model, we consider light generated by many atoms each making the same transition. During each transition, a ...

How can my window not scramble the image of my yard?
How can an image pass through a window if the atoms in the glass randomly emit photons in any direction?
I've read that glass is transparent because the atoms don't readily adsorb visible light, so it ...

Explain reflection laws at the atomic level
The "equal angles" law of refection on a flat mirror is a macroscopic phenomenon. To put it in anthropomorphic terms, how do individual photons know the orientation of the mirror so as to bounce off ...

Principle of Reflection on atomic level
This well-observed phenomenon has, besides several others, always been a fascination to me. We are well aware of several theories, experiments, and practical applications of this well-known phenomenon,...
