Is it possible to measure the temperature of a candle by the diffraction method?
I am reading a book " Physics, Fun and Beyond" by Eduardo de Campos Valadares. In his book, he is mentioning about an experiment "bending laser beams with hot air." I am posting a ...

Can we explain certain light phenomenon like refraction using particle nature of light?
Using Hugyen's principle and wave nature of light, refraction, diffraction are relatively simple to explain but I have been visualing a mental model for a couple of days where the photons on reach the ...

Can the colors of white light be separated through reflection alone?
Can the colors of white light be separated through reflection alone? My answer to this is no since if we want to separate the colors, we use prism and when light passes through a prism, the dispersion ...

Double slit experiment in water: A simple demonstration of refractive wavelength?
The speed and wavelength of light both reduce in media with high refractive index.
However, it is perhaps not intuitively clear how frequency and wavelength behave in refractive media.
A very simple ...

Diffractive peak for high-frequency scattering from a sphere with small index of refraction?
How does a transparent sphere's shadow fade as $n\to 1$?
Consider radiation of wavenumber $k$ incident on a transparent sphere of radius $a$ and index of refraction $n$ in the limit $ka \gg 1$. (...

Optics question: Simple way to transform a parallel bundle of collimated beamlets into a converging (diverging) bundle of collimated beamlets?
I'm searching for an optical element that converts a parallel bundle of individually collimated beamlets into a converging or diverging bundle of still collimated beamlets (or vice versa). So ...

Refractive Index of a Aspheric lens
I have the following specifications of an aspheric lens:
AL5040-B - Ø50 mm S-LAH64, f = 40 mm, NA = 0.54, ARC: 650-1050 nm
Is there a way to calculate or identify the refractive index of the lens ...
