Struggling with interference [duplicate]
I was reading the book optics by zajac and hecht. It was a nice one until physics optics, i got that interference becomes when the light is coherent and monochromatic, and it is the superposition of ...

Propagation of two non-parallel waves
When a transverse wave is described by the equation, $y=A\sin(kx-\omega t)$,it is immediately meant that the direction of propagation is the $x$ axis with $y$ axis as the displacement. And we know ...

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 ...

What is the meaning of this statement in Optics, Born-&-Wolf regarding coherence length?
In their treatise "Principles of Optics", Max Born and Emil Wolf state in the section on coherence length (page 317, para 1) that:
...... as the difference of optical path is increased, the ...

What's the physical origin of bound states in the continuum (BICs)?
From my point of view, BICs are modes built by destructive interference. But I'm confused about the orgin of BIC, I have two questions:
The differences between BIC modes and defect modes.
It has ...

Why there is always a bright fringe at angle zero in light's double-slit experiment?
The explanation I read is that because at $\theta = 0$ the waves travel the same distance from both slits to A and thus have no phase difference. They add up constructively so there must be a bright ...

Do perpendicularly polarized waves interfere?
In the MIT ME optics OCW slides, it is written that parallel polarized waves do interfere but perpendicularly polarized waves do not interfere. However, isn't circular polarization formed by the ...

Finding the phase difference of two interfering waves
A system illustrated in the given figure consists of two coherent point sources $1$ and $2$ located in a certain plane so that their dipole moments are oriented at right angles to that plane. The ...

Imaging aberration
Qs: Doesn't a curved side lens produce less aberration than a flat lens in general because the overall angle of deviation is smaller in the curved lens?
Consider the following experimental results ...

Do different kind of waves in a medium interact with each other?
Say for example, air and sound can both propagate to air. Now, suppose we have a sound and light wave travelling close by, how would the two waves interact with each other? Suppose I made a very large ...

Do we take into account the physical angle between Electric fields and Magnetic fields during interference of light?
I have been studying interference of light waves for a while now and I have a doubt.
I have never seen any sources (books, internet , teachers) ever take into consideration about the "actual"...

Are two lights waves that are out of phase mirror images?
Is light shifted 180 degrees out of phase, when it is reflected off a mirror?
When light is shifted 180 degrees out of phase, is it the mirror image of the light wave?

Diffraction grating: Why does the light need to be in-phase?
I am currently studying the textbook Infrared and Raman Spectroscopy, 2nd edition, by Peter J. Larkin. Section 1.1 Dispersive Systems of chapter 3 says the following:
A monochromator consists of an ...

How to properly calibrate phase axis to represent an optical interferometric stability curve?
Assume we want to measure how stable an interferometer is.
We send two ultrashort pulses (left figure), delayed by the fixed time $\Delta t=T$ relative to each other, into a spectrometer to observe ...
