A protractor at the bottom of the mirrors (pivoted strategically to one of the mirror) shows the angle between both the mirrors! In front of/between the two mirrors an object to be reflected is placed!
As the mirrors converge more and more reflections of the object is seen! At any point of time number of objects seen will be equal to:
360/Angle between the mirrors
For example:
- 0 degrees: Infinite!
- 15 degrees: 23 reflections + 1 real object (Total: 24)
- 30 degrees: 11 reflections + 1 real object (Total: 12)
- 45 degrees: 7 reflections + 1 real object (Total: 8)
- 60 degrees: 5 reflections + 1 real object (Total: 6)
- 90 degrees: 3 reflections + 1 real object (Total: 4)
This exhibit was not capable of showing 0 degrees due to both mirrors being hinged at center!
