Refraction by a thin lens
What happens if the radii of curvature of the two spherical surfaces of a thin lens are equal?
According to the formula,
$$1/f = (n - 1)(1/R1 - 1/R2) $$
(Where $n$ is the refractive index of the ...

Finding a path of beam in a gradient-index media
I'm trying to find a polynomial that describes a path of a beam in a gradient index media.
It is a path of least time (Fermat's principle) meaning that it takes path that takes the least time to get ...

Equations of Fermat's principle/Snell's law in a gradient lens (sugar aquarium)
I'm trying to animate a beam of light inside a substance with gradient index of refraction as a function of y. A good example of that is a syrup inside an aquarium like here https://www.youtube.com/...

Integrating over Snell's law with a varying index of refraction [closed]
I am working on a research practical and I encountered the problem of having to integrate over Snell's law. The exact problem is that I have a varying index of refraction, which is a function of the ...

The impact of refraction on a double slit interference pattern
Source: isaacphysics.org
This set up, without the glass, would produce a standard interference pattern, with a bright central maximum followed on both sides by progressively dimmer maxima.
Placing a ...

Looking at spherical air bubble underwater [closed]
You are underwater, looking through a spherical air bubble. What's its actual diameter?
As you can see from the picture, there is no goggles to cause refraction. So how will the bubble's size be ...

When are the reflectance R and the transmittance T equal to each other at normal incidence?
Really struggling with this one.
Under what conditions would the reflectance R and the transmittance T be equal to each other at normal incidence at an interface? What would be the values of R and T ...

Fermat's principle in exponential refraction [closed]
Determine path light will travel in a index of refraction described as $n(y)=1+be^{-ry}$. Let the light start off at the origin (0,0) and go to the point (L,0). Determine the equation that must be ...

Help With Calculus of Variations
I've been given the problem
"Use Fermat's Principle to find the path followed by a light Ray if the index of refraction is proportional to $y^{-1}$."
Honestly I'm not too sure at all how to begin....

What is the refractive index of glass for 1 photon?
Refractive index of glass for the VIS light is about 1.5, meaning that light will be reflected with some ratio (say 0.04, if we have normal incidence and semi infinite media). It is obvious for many ...
