Angle Between Mirrors

Angle Between Mirrors Model – Multiple Image Formation Demonstration | Manufactured by Samtech Instruments

The Angle Between Mirrors Apparatus by Samtech Instruments is a physics optics demonstration model used to study multiple reflections and image formation using two plane mirrors placed at adjustable angles. It helps students clearly visualise how images increase when the angle between mirrors decreases.

Description
The apparatus consists of two high‑quality plane mirrors mounted vertically on a protractor‑marked base so the angle between them can be accurately measured and changed. Colored geometric objects are placed between the mirrors to clearly observe repeated reflections.

Working Principle
Light from the object reflects repeatedly between the mirrors, forming multiple images.
The number of images depends on the angle (θ) between the mirrors and follows the relation:
n = (360° / θ) − 1
A smaller angle produces more images, while a larger angle produces fewer images.

Educational Concept
This model demonstrates laws of reflection, multiple reflection, symmetry, and image formation. It also explains the working principle of devices like kaleidoscopes and optical mirror systems.

Educational Applications
Suitable for physics practical labs, classroom demonstrations, and science exhibitions. Helps students connect theoretical optics with real visual observation.
