Luneburg lens in a medium
A Luneburg lens is a spherical lens with a gradient refractive index. It has the interesting property that light coming from focal length of infinity will be focused on the surface of the lens.
The ...

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 ...

Calculating mirror size for a teleprompter
I'm trying to calculate the required size of a mirror for a teleprompter application. The goal is to use the smallest possible mirror while still capturing the full image.
It's a straightforward setup,...

Why aren't all objects and their images same in size?
Suppose there is an object in front of a convex lens and we know that the light rays from each point on the surface of object will converge at a different point and form an image. So that means that ...

Directionality of laser light in vacuum [duplicate]
It is well-known that laser light is directional because of coherence from stimulated emission. This means that the light is emitted ONLY in the direction of propagation, and not in any type of ...

What does the optical Hamiltonian mean?
So I was trying to demonstrate Snell's law with Hamilton's equations, and when I got the Hamiltonian:
$$H = -\sqrt{n^2-p_{1}^2-p_{2}^2}.$$
I had a question about what this Hamiltonian indicates. I ...

Intuitively understanding virtual images in a multi-(thin)lens system
Let's say there is a multi-lens system of a converging lens (ex. a biconvex) and then a diverging lens with an object on the left of the system. And furthermore, let's say that due to the specific ...

Is there ways to find the most efficient geometrical structure for sunlight concentration? [closed]
we are researching for the most efficient geometrical structure of a concentrator. What we mean by 'most efficient' is that we are trying to get the most sunlight while sun is up. We are not trying to ...

What exactly happens to a light ray that is incident on the vertex of 2 mirrors inclined at some angle
So the question I had was that if we have two mirrors as shown in the diagram, what exactly occurs to the light ray that is incident on the vertex of the mirror? If we would like to construct the ...
