THAT IT HAPPENS?

 

The kaleidoscope is a very old optical toy, nevertheless officially it was not patented and presented as we nowadays know it until year 1816 on the part of David Brewster, a Scottish physicist.

In the base opposed to the one of the viewfinder are all those elements that will create what soon we will see (that is to say: the perforated slips of paper and the accounts). Now we think that we are in front of a kaleidoscope of three mirrors, then the base will be triangular, the reflection will be locked up by these three mirrors, which will reproduce everything infinitely what appears in center of the same. When looking at the viewfinder we see a reproduced figure hundreds of times by these 3 mirrors that are reflected some to the other creating an infinite vision of a mirror within a mirror. The distance (in degrees) between the mirrors creates different reproductions than we found in center. With this example when the mirrors are to 45grados one of the following one are created eight duplicated images, when they are to 60 degrees become six and when these are to 90 degrees see four.
