How will Newton's rings look using a Concave-convex lens?
I want to examine lenses that are concave-convex (one for each side) using the Newton's rings method.
I'm trying to build the theoretical model for this, but I'm quite sure that the rays of light will ...

How is light interference explained with photons?
In the classical model of light as an EM wave, interference is a trivial consequence of the linearity of the wave equation. Now, if we model light as collections of photons, how is light interference ...

Interference pattern due to a thin prism and a lens
We have a setup like this where a converging lens placed between inclined face of thin glass wedge and a screen. The screen is parallel to the inclined face of the wedge and the optical axis of the ...

What determines how much power goes into each diffraction order?
Imagine a grating with infinite number of slits, and the spacing D between slits is larger than the wavelength so that there are high order diffractions. In each of the diffraction directions the ...

Why does collimated light form an airy disk pattern on a camera sensor?
I'm using a Raspberry Pi camera v2.1 (lens removed) to make some observations on a laser. I have the laser coupled into a single-mode fiber which outputs a smooth gaussian spread onto the camera. From ...

Focusing lens placed after double slit experiment
How would the expression for the intensity distribution produced by a double slit on a screen change if a focusing lens of focal length $f$ were placed a distance $f$ in front of the screen?
The ...

Number of fringes obtained on interference of light of different wavelengths [closed]
The Question goes as follows:
I am stuck at the part where we obtain general equation for path difference of two interfering lights. Since wavelength of those interfering lights are different, so I ...

Jamin interferometer's interference pattern
I'm working with a Jamin interferometer, and I'm interested in calculating the intensity pattern I would observe in a far away plane. The scheme is as follows:
Spherical light enters through the ...

Double slit experiment with polychromatic light
When double slit experiment is carried with white light , the resulting pattern on the screen is predicted by assuming white light as combination of light of different colors. Then it is assumed that ...
