Mirror Reflection: Seeing Double?

    Mirror Reflection
Click For Summary
When two identical mirrors are placed next to each other at the same level, standing in the middle will result in seeing reflections from both mirrors. If the mirrors are perfectly parallel, each will show one reflection, but if they are not, an infinite regression of images can occur, creating a visual effect of multiple reflections. This phenomenon is often observed in places like barber shops and elevators, where mirrors are positioned to create interesting visual effects. The angle and alignment of the mirrors significantly influence the number and arrangement of reflections seen. Understanding this can enhance the appreciation of mirror placements in various environments.

Hello all,

I have a quick question. If i put two identical mirrors right next to each other on the same surface at the same level and stand in the middle of it will i see two of me or will it act like looking myself if that mirror was one single piece.


Thanks!

You mean one mirror in front of you and one behind? If they are perfectly parallel, you'll see one reflection in each mirror but only if all the other copies of you are completely eclipsed by the one in front. If you lifted your arm and waved at yourself, you'd see an inifinite regression of arms waving - to the limit of the mirrors reflectivity.

You see this all the time in barber shops.
 
My favorite local pizza restaurant (where I spend too much time to be good for my waistline) has mirrors on facing walls. The mirrors are not quite parallel, so I see a sequence of many images, gradually curving upward until they "disappear" beyond the top edge of the mirrors.

Yep. In reality, the mirrors are rarely parallel, creating this curving effect.

Another common place: elevators with mirrored walls.
