Modified two slit diffraction experiment
I thought up a slight modification to the classic two-slit experiment that would be fun to try, but I am certain that I am not the only person to consider it, and would like to know if it has already ...

How practical double slit experiment deviate from the young double slit experiment given in a basic physics textbook?
How practical double slit experiment differ from the young double slit experiment given in a basic physics text book? Will there be any difference in the appearance of fringes ? An elaborate ...

Amplitude of light in double slit experiment
While reading about double slit experiment I have found no article where the amplitudes of light at the board ( on which light falls) is calculated . Only the fringe width and intensity ratios are ...

Diffraction of a double slit where the slits are far apart
I'm trying to figure out how I can possibly know the real equation of the intensity of the diffraction pattern of a double slit (I don't care about interference for now). Here are my thoughts:
...

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 ...

Why diffraction is not happening?
Recently i encountered a problem on the Young's Double Slit Experiment. The question was paragraph and had multiple sub-parts on the different variations of the experiment.
One of them was about what ...

Young's double slit experiment with two glass slabs
Suppose I place two glass slabs with different thickness and refractive indices in a YDSE setup. I was told that if
$$ (\mu_1-1)t_1=(\mu_2-1)t_2 $$ then there would be no change in the interference ...

Why in the experiment of double slits, in case of radiation of wavelength of red light, we can observe an envelop of the minimum?
I have made an experiment in which i have to measure the intensity of the light generated by an $\text{He-Ne}$ laser, in the case of two slits, I pretend to observe an interference lattice.
I have to ...

Necessity of Coherence for Interference in the Context of Indistinguishable Photon Paths
I've been studying the interference phenomena observed in the double-slit experiment and came across a concept that piqued my interest. It is well understood that for interference patterns to form, ...

Calculating net phase in single slit diffraction
I want to calculate the net phase at a point on the screen in Fresnel diffraction. Attached below is a rough diagram if needed.
For this I considered hypothetical $n+1 $ small slits acting as sources ...

Shift in image caused by refraction in normal image formation and shift in fringe (youngs double slit experiment)
for shift in a image from its original position due to a slab of thickness $t$ and refractive index $u$ is given by $shift(s)=t[1-1/u]$
and for shift in fringes formed during youngs double slit ...

Double slit diffraction integral?
In our physics class, the professor went over a so-called "diffraction integral" for single slit diffraction:
$$E = E_0\cos(kx - kct)\qquad\text{then we ignore time dependence}:$$
$$E = E_0\...

Slit size vs. object size in double slit experiment
In classical optics, the double slit experiment show interference of light. The spacing of the fringes at a distance $z$ from the slits is given by
$$
w \approx \dfrac{z \lambda}{d} \;,
$$
where $d$ ...
