Quick Answer: The Infinity Well Model is an optics demonstration in which successive reflections produce repeated images, giving the illusion of a well that extends far deeper than its actual depth.

Key Features
Demonstrates multiple reflection of light
Shows repeated image formation between reflective surfaces
Creates an apparent-depth illusion
Suits group viewing in classroom demonstrations
About This Product
Students view the model from its intended observation position and see the image repeated again and again, as if the well had no bottom. Teachers relate this to successive reflections between reflective surfaces and use it to explain image formation, apparent depth and mirror-based illusions. It suits physics lessons on light and supervised exhibition displays.
Frequently Asked Questions
Q1. Why does the well look endless? Light reflects back and forth between the reflective surfaces, and each reflection forms another image. The row of repeated images gives an impression of depth far beyond the real model.
