### 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 ...

### Can a real object also be considered as a real image if the direction of rays were to be reversed?

I came across the concept in a book wherein a real object is classified as a body that emits diverging beams of light; whereas the virtual objects are a point or a collection of point where the light ...

### Is there an exact correspondence between Seiberg-Witten theory and mirror symmetry?

Seiberg-Witten solution gives an algebraic geometrical description of the quantum moduli of 4d $\mathcal{N}=2$ SUSY gauge theory. However, the solution seems purely constructive and does not enjoy ...

### Plain mirror reflection confusion

Can anybody help me reconcile my understanding of plain mirror reflection with what is said in this video? instagram video My understanding is that image size is always the same as object size but in ...

### Should I canculate the instantaneous velocity of average velocity for the question?

A man running at a speed 5m/s is viewed in the side mirror of radius of curvature R=2m of a stationary car. Calculate the speed of image when the man is at a distance of 9m from the mirror.

### How do virtual images make any sense?

If the light meets behind the mirror, without really meeting, how is it even supposed to be interpreted. If two light rays never meet because they are diverging but they meet behind the mirror-which ...

### What would it look like inside a spherical mirrored room?

What would it look like if you were inside a perfectly spherical "room" that was completely mirrored (seamless) with a small, single source of light? Previously I'd wondered/theorized about ...

### Incongruence in virtual image position on a convex parabolic mirror

I'm pretty new to the subject of geometric optics so forgive me if what I'm asking has a trivial explanation. I was trying to find the position of the virtual image of a point object on a convex ...

### What can be used to change the direction of the laser beam? [closed]

Let's say we have a laser beam coming from a source called X, we would like to change its direction so that it would hit directly on the object that we have. What would be the possible solutions?

### When should we draw Mirror Extension to show Line of Symmetry

In the attached image, the mirror extension is drawn to show the line of symmetry to solve this question. My doubt is that under which condition, we should draw the line of symmetry.

### Thought experiment on plane mirrors

I was just doing this thought experiment: Consider a well illuminated cubical room with all its inner six faces as mirrors. Now we place an insect inside the cube and it starts moving on the floor of ...

### Is this a correct non-technical description of mirror symmetry for Calabi-Yau manifolds arising from string theory?

In string theory there are physical reasons why the space we live in must locally be the product of Minkowski space with a Calabi-Yau manifold. The general theory doesn't say which Calabi-Yau manifold....

### What would I see if I locate myself in one of the focus of an ellipsoid whose surface is mirrored? [closed]

Imaging a 3D ellipsoid whose surface is completely mirrored. According to the optical laws of the ellipsoid, all the rays that start in one of the focus, end up forming an image on the other. I was ...
