Quick Answer: Light Reflection Demonstration Apparatus is a manual physics instrument with a reflecting surface on a marked base, used to identify the normal and test the laws of reflection.
Last updated: October 2026
Key Features
Reflecting surface positioned on a marked experimental base
Angular scale or graduated base for angles measured from the normal
Mirror or incident ray can be repositioned for repeat readings
Single reflecting-surface arrangement
About This Product
Secondary, senior-secondary and introductory college classes use it to trace incident and reflected rays at several angles and compare each pair of readings. Its Light And Optics role is the law-of-reflection practical, where the normal is drawn at the point of incidence before both angles are measured.
Frequently Asked Questions
Q1. What concepts does the apparatus demonstrate? The incident ray, reflected ray, point of incidence and normal, and the rule that the angle of incidence equals the angle of reflection when both are measured from the normal.
