infinite camera

[elpenmaster]

i have a question
i took my handycam and pointed it at a mirror. i turned the LCD screen so that what i saw through the camera in the mirror was the LCD screen
i saw several screens, and then the focus failed and i just saw an aquamarine color
if the focus was perfect, what would i see? it would go on to infinity, so would i start seeing pictures from when i first pointed the camera at the mirror? what is being filmed? :?

this is probably not the right place to ask this, but. . .

Yes, you would see lots of screens inside each other.

[elpenmaster]

Of course

but what would be inside of the screens?

or would there be nothing inside of the screens because since each screen is smaller than the one before it, and there are infinite screens, there is zero space inside of the smallest screen, because it would be infinitly small?

[Keiji]

The smallest screen would contain whatever color was on the camera before (because light rays take a finite amount of time to travel).

If you point it perfectly at a 90 degree angle at the mirror, you would eventually see a black screen until the energy of light dissipates.

[Geosphere]

RQs right. Each succesive screen is dimmer.

[elpenmaster]

but what if the mirror was perfect and it reflected every single photon?
i dont think there is a smallest screen, because there are infinite cameras

[Keiji]

Then my last post will be correct.

[PWrong]

1. Something has to emit the light at a certain frequency, and therefore a particular colour. If yellow light bounces off a mirror or a screen a billion times, it will still be yellow.

2. If the camera is pointed at exactly 90 degrees, the light will never reach your eyes because it's trapped between the camera and the mirror.

3. As you get closer to 90 degrees, the distance between each screen gets smaller. At exactly 90 degrees, every screen is hidden behind the first one.

That would only be true if all rays of light concerned were perpendicular.

Thats not the mirror. You're talking about perpetual motion at that point.

So, no. The photons themselves lose velocity.

[Keiji]

Ehh, photons always travel at a constant speed, and never lose energy. duh.

[Geosphere]

duh

[Keiji]

Don't spam.

[RQ]

wouldn't the light energy dissipate over time, it's infinite u know.

[Keiji]

If the light rays were perfectly parallel, they would NOT dissipate. This is how lasers are made.
