please be specific about the number of mirrors I have to use and how large they should be and what angles they should be placed at. And how much light and where should I shed. Thank you. I also made a stupid doodle which I thought might help
I think the given solution is wrong.
The lens forms image at ##(+75,0)## which is ##25 cm## from pole of the convex mirror which acts as virtual object for mirror.
It is true that the reflected ray is rotated by ##2\theta## as in case of plane mirror. Rotation of Spherical Mirrors
But that...
Imagine a special box made of inward facing mirrors. These mirrors have zero mass and are perfectly reflective. A single photon is inside the box bouncing from side to side between the two mirrors of the sides of the box. The photon is perfectly preserved in this state, and loses no energy...
I must add, that, when used in a lit space, or in daylight, spraying before the mirror does not make any light rays visible. Is it simply a matter of light scattering?
Also, I am not sure whether this question belongs here or in classical physics.
I am trying to build a Fabry-Perot interferometer to make some narrow band filters, and I was wondering if anyone can go into the specifics of whether there's anything special about the types of mirrors used in construction.
I started by trying to see how hard it really is to make one on my...
For this problem,
The solution is,
I don't understand how if ## \gamma < 0## then there will be multiple reflections? I don't understand how ##\gamma## can be negative.
Many thanks!
Hi guys, i am Nenad Komjenović from Bosnia and Herzegovina, I am just a regular guy, who likes geeky stuff and i don't know physics, so i wanted to ask you guys for an opinion. I was inspired by the "Markus Kayser - Solar Sinter Project" Youtube video, in which the guy used fresnel lens to...
I'm currently confused in determining whether an image formed by the 1st mirror (the left one) is a real or virtual object for the 2nd mirror.
Here is the solution manual:
This is what I have in my mind:
Since the object is located between the focus and radius point of the first mirror, the...

Here is a concept suggesting reactionless drive:
Setup: A light pulse of wavelength l0 bouncing between 2 mirrors one on the left - ML and one on the right - MR. Each mirror oscillates perpendicularly to light travel direction attaining relativistic speeds vl, vr. Light pulse is timed so it...
Parabolas are the only geometrical shape in which we have a perfect focus (not an approximate one) and does not depend in the angle of incidence being small. So, why do we even build spherical mirrors and not only parabolic mirros?
I did a little experiment recently where I took a plane mirror and held it underneath a ceiling light. Then, I began to lower my head so that my view was closer and closer to the surface. When I did this, the image of the light began to drift lower and lower in the mirror until it completely...
The setup of the problem is shown in the image below.
I know that I must add all the contributions of each reflected ray and that its amplitude will be reduced by a factor ##r## each time it is reflected. So after the n-th reflection, its amplitude will be ##E_0r^n##, with ##E_0## the amplitude...
Hi,
So there is already a written solution which I have, but this is more a question about why we omit reflection that come back to the same mirror?
Method:
Let us consider one of the mirrors, we know it will emit a heat flux given by: q_{1} = \epsilon_{1} \sigma T_{1}^4 . Given that we are...
What is a mirror? How it reflects the light?All this knows. The Mirror this smooth surface from hard material. Most of all the metal approaches for its fabrications. Than more smooth mirrors surface, that more light it reflects. In ideal this 100%. Now we look at mirror closely. We see the...

I was wondering if you look into a set of compound mirrors (imagine a mirror along each of the planes on the x y z axes) how would your eyes appear if the image reflected was reflected off all three mirrors. I understand the reflected light is parallel to the light before it hits the mirrors...

Hi All.As I understand it:The main limiting factor on a telescope is the size of the main mirror. Bigger mirror = more light collected = better quality image. Due to problems with manufacturing mirror size, or at least mirrors of good enough quality, is limited to a few metres.A quick ponder...

Magnification
|M|<1 = smaller
|M|>1 = larger
This is my reasoning because the magnification is -d0/di so it is the ratio that matters. Because wouldn't the sign just affect the type of image?? If you consider the sign in image size, you are saying that only one type of image (real/virtual)...
Hello,
A light pulse moving bouncing between two mirrors (top and bottom) follows a vertical straight path w.r.t. to an inertial observer at rest relative to the mirrors. However, a moving inertial observer see the light pulse move in a zig-zag path as it bounced back and forth between the...
I'm confused about something regarding phase shifts but I'm not sure I've pinned down what.
I had always thought of a mirror as introducing a global phase shift of π in the position basis, but I only now realize that this makes no sense: of course -A ⊗ B = A ⊗ -B, so a global phase shift is not...
Special relativity is replete with examples of turning mirrors into clocks. Place two mirrors across from one another, bounce light between them, and measure the time.
But as I thought about this, when a photon hits the mirror, it is absorbed by an electron which moves to a higher energy...
The mirror that I'm talking of, is situated in Hazarduari Palace in Murshidabad, West Bengal, India. This place was once the capital of Bengal under the Nawab before the British defeated the Nawab in the historic battle of Plassey, 1757.

I was reading a pdf that mentioned a quantum-controlled beam splitter and wondered whether a quantum-controlled mirror exists. In the beam-splitter case, the beam splitter could either be present or absent, such that path information of photons was either preserved or not. It was controlled...

Emission theories propose that the velocity of light depends on the velocity of the light source. But the ordinary Doppler effect assumes the velocity of light remains as ##c## with respect to the ether medium, even when the light source is moving at speed ##v## with respect to the ether. They...

Hi.
In a Mach-Zehnder interferometer, there are mirrors in both paths. When a photon gets reflected on a mirror, it transfers momentum. Also, mirrors are classical objects that are usually not assumed to exist in superposition states.
Shouldn't it (at least in principle) be possible to measure...

Hi experts,
I am aware using prisms enable total internal reflection while using mirrors there is only reflection of light. The difference is that in the former there is 100% light intensity after reflection while the latter does not.
I have also read that using prisms is better than using...

A telescopes sensitivity, or how much detail it can see is directly related to the size of the mirror area that collects light from the objects being observed. So a bigger mirror means higher resolution so you can see more detail at greater distances right? does it also mean it can collect more...
