IF YOU HAD ROOM WITH ABSOLUTELY NOTHING IN IT AND THE WALLS CEILING AND FLOOR WERE MADE OF MIRROR WHAT WOULD IT LOOK LIKE IN THE MIRRORS
Holy shit I asked my dad who’s a physics teacher and he just looked at me, looked at the table, looked at me, tried not to smile, looked angry, and started to look up where you can buy big mirrors.
this is an actual room of mirrors.
as you can see, it leads to glitches in the matrix
It wouldn’t look like that. That room has a mirrored table and chair in it. I feel obliged to point out that if there’s absolutely NOTHING in the room, i.e. no light source, you wouldn’t see shit. Let’s say there’s a just a filament camera for your viewing pleasure, and a teeny-tiny diode equivalent to a 60-watt lightbulb.
What you would see, less cluttered, would be a series of “cells” the shape of your room, receding into the distance, getting progressively dimmer, and also less distinct.
Why less distinct? Because of the dual surface: the silver backing, and also the front of the glass. Each time it reflects, there’s a double-image.
Why dimmer? The light is not in phase —that is, it does not radiate like a laser. Each time it reflects, it radiates in a cone shape, and there’s less light available to form the image each time it runs into a new surface. Also, the mirrors do not perfectly reflect all light. They can’t, for a variety of reasons. They absorb some of it. Here are some things I’m thinking. I’d appreciate a proofreading, if anyone’s bored.
- The glass is not 100% transparent. And it usually has a slight tint to it, that optics manufacturers work very hard to minimize and neutralize. 100% efficient mirrors are not physically possible. Even the best mirrors we can make are only 99-and-a-fraction reflective. 100% is not even theoretically possible, I don’t think. We’d just keep adding decimal places (although stupid math tells me that if you added .9999~ for infinity, that’d be the same as 1). In a room made with 85% reflective mirrors like the ones we all have, a light beam would lose 15% intensity each time it reflects. It’d reflect 85% on the north wall, and then be down to 72% strength (85% of 85%) on the south wall, and then 61, 52, 44, 38, 32, 27, 23, 20, 17, 14, 12, 10… fuck, too small to see.
- also, the later reflections are getting too dim and small (next to the earlier brighter and larger reflections) to be seen in the glare. That’s why it’s much easier to stargaze during a new moon.
- there is microtexture to both the glass surface and the silvering
- the “farther” (in vector) it gets from the ultimate source, the LED, the more light scatters through the air, or, assuming vacuum, disperses into its natural light cone. Light touches the surfaces obliquely, and eventually at such a low angle that the texture of the surface is high enough to capture it. Practical effect: the reflections of the LED get darker, but also the black between the white dots gets grayer.
- some light would find its way into the seams
- Some light would run back into the LED.
- Final effect, loss of light: the room gets warmer.
