Quick Answer: The Concave Mirror is a concave spherical mirror for ray optics practicals, used to show converging reflection, find focal length and study real and virtual image formation.
Last updated: October 2026
Key Features
Inward-curved reflecting surface brings parallel rays towards a focus
Forms real, inverted or virtual, upright, magnified images depending on object distance
Used to locate the focus and apply the mirror formula
Works with ray boxes, optical benches, holders and screens
About This Product
Set in a holder or on an optical bench, the mirror is aligned with a light source or distant object and a screen is moved until a sharp real image appears. Measuring the mirror-to-screen distance gives an estimate of focal length, and changing the object distance shows how image size and orientation change. Results are compared with standard ray diagrams for pole, focus and centre of curvature. Besides buyers across India, the Concave Mirror can be exported to institutions in Fiji, Papua New Guinea, Luxembourg, Jordan, Ghana and Republic of the Congo.
Frequently Asked Questions
Q1. Can a concave mirror form both real and virtual images? Yes. Depending on the object distance, it can form real, inverted images or virtual, upright, magnified images.
