I don't know,if this has been posted before.I hoped not.

You are in the room without windows and hermetically closed(smooth and without clefts).The room is cylindric and covered with mirrors.How many reflections of yourself you can see?

Probably 0, because there wouldn't be any light in there

- the centre is the focal point if it is a circular (not ovoid) cylinder. So the question is where are you sanding???...

further thought... Windows can be reflective, could be glass/mirror too, hermatically sealed - so can't stay in there too long, but long enough to find out if the ceiling and floor are covered in mirrors

Maybe I miss something obvious, but is there more information??

well, I was thinking of that too, but why go in without a light in such conditions?

Yes,you missed.Stop roaming lost in space and stop for a while on the Earth to relax.Not everythink is so complicated.

Assuming you are standing in the exact center of the room, there is enough light to see, and there are a flat floor and ceiling that are both also mirrors, you see three reflections of yourself.

One streching all the way around the walls (no reflections of reflections because you're blocking the other side), and one each on the floor and ceiling.

Come to think of it, in that situation you could look up on the wall and see your reflection from the ceiling to the wall...

Perhaps I should assume only what is told in the OP. So my answer is one reflection - the one streched all the way around the room.

Because is a puzzel.Maybe the man was forced to goes in,but doesn't matter,that's the condisions and the answer is 0.There is no light.

Was written,that the room is hermetically closed and without clifts and windows-in this case from where came this "enough light to see".Under the given conditions the room is totaly dark.

Well, assuming there is enough light to see, I would think there would be an infinite number of reflections

yep.

either infinite with light or none with no light.

What would the answer be if you were enclosed in a perfect sphere (that is lit for seeing purposes somehow) and the entire inside of the sphere was a mirror?

Would position and angle really matter if you are inside a sphere of mirrors? :huh:

I think that's true if only the wall is mirrored.

OP says "The room is cylindric and covered with mirrors."

that's something to think about - walls and ceiling mirrored too.

Another thought will there be infinite reflections above and below, will that be infinite x 2? (or if you take one away is it infinity x 1/2?)

A parados question comming up!
