How do I slow down photons so they are as fast as the speed of sound ?

Using materials with a high enough refractive index. Or if you only care about group velocity then using photonic crystals. Either way you probably need metamaterials.
Owen Davis
Say I have the metamaterials, how much can I slow a photon down, and would it be still visible to the human eye ?
Luke Parker
It depends on the meta materials you have.
Usually people only care about slowing the group velocity, so I'm not sure what kind of reduction you could get in phase velocity, but without using cryogenic chambers or equally elaborate setups you can probably reduce it by a factor of 100 or so.
>would it be still visible to the human eye ?
Unless the wavelength has been changed then yes, if the photon hits the eye it will be detected.
Asher Johnson
Using the power of your mind. You must believe in yourself.

>photon
Photons don't actually exist. If you mean protons or electrons, you just need to shine them through consecutive prisms.

You have to build a sound wall to keep illegal photones from moving faster than sound
Charles Powell
How about you don't slow them down, and let them get on with their daily lives, mkay?

Alternatively known as time crystals

Build a black sun (black hole). Apparently their gravity slows down and even stops the speedy photons.
Evan Baker
They don't really slow down btw, they are just absorbed and released so the apparent effect is to slow down.
When photons are traveling, which is pretty much the only thing they can do, they are still at speed of light.
Noah Carter
Anybody here remember slow glass?
Anthony King
>would it be still visible to the human eye ?
A photon is only visible if it hits your eye. Anything is visible if a photon reflects off of it and that photon hits your eye. To ask what a photon looks like, is like asking what a sound wave sounds like.

Mason Bennett
refractive material just make the path of the photon longer, but itll still move at c
Aaron Wilson
But that's wrong.
Justin Reed
he is right tho, photons are just condensed packs of info/energy in the space medium, the very principle of modern wave/particle theory
Nicholas Nguyen
By that logic electrons don't exist.
Gabriel Thomas
>implying electrons arent just charged photons
Charles Russell
Cooled gases? idk
Jason Lewis
>implying they are
Joshua White
i dont know, all that matters is if it still has
enough energy to activate photoreceptors. I know for sure that making light waves wider (ergo longer, ergo less frequency) reduces energy
If it reaches the frecuency of sound i doubt it could be seen and it would act like radio waves, having Jeb! tier energy
If it loses energy itll probably be se

>implying an electron is anything other than a free down-quark
Evan Moore
made me smile
Jaxson Scott
at a glance all the replies are incorrect.
if you want to slow down light it must be passing through a bose einsten condensate (REALLY REALLY COLD STUFF)
Liam Allen
Because thats a practical solution.
Good luck creating one outside a lab.
Eli Thomas
would it change the wavelength ?
Christian Bennett
>i like solitons
me too
Aaron Watson
If you did would they gain mass?
Noah Lee
You literally can't. You can slow the speed that light propagates thru a space by forcing it thru a medium such as water or a bose-einstein condensate, but every photon always and only travels at c. What you'd be doing is causing the photons to be absorbed and re-emitted as it passes thru the medium, it's not the photons that are slowing down, just the "light wave".
John Torres
Not necessarily

Evan Myers
I wonder how it feels to see a light from a very very slow photon.
Easton Price
The same way you slow down any energy, change its frequency
Isaiah Hughes
you cannot actually slow an individual photon, but you can bounce multiple photons through a material and it takes them longer to cross the material.
Luis King
>bounce multiple photons through a material and it takes them longer to cross the material
WRONG
Look up what a polariton is.
