itsa reflecting telescope
I'm not sure by what you mean, but maybe a kaleidoscope?
There are at least 2 plane mirrors at some angle to each other in a Kaleidoscope, in order to create the symmetrically-multiple images that is the instrument's point.
Mirrors help illusions because mirrors make stuff look like if nothing is there.
because they reflect
depends on what instrument you are talking about
Plane mirrors do not create images that can be placed on a screen, only concave mirrors can.
mirrors and/or lenses
The paradox of mirrors refers to the infinite reflections that occur when standing between two parallel mirrors facing each other. The reflections create a seemingly endless tunnel of images, giving the illusion of infinite space despite the limited physical dimensions of the mirrors.
