Concave Mirror Glass
Product Code : JA-PLE-4214
Concave Mirror Glass (SKU JA-PLE-4214) is an optically worked spherical glass mirror, silvered on the back with a protective coating, used to study real and virtual images formed by reflection. It is supplied in 50 mm and 75 mm diameters with focal lengths from 50 mm to 300 mm. This concave mirror for physics lab practicals is a core item for focal-length experiments in secondary and senior-secondary classes and in college optics laboratories.

Applications of the concave mirror in physics practicals
The concave mirror is used to find focal length, first roughly by focusing a distant object and then accurately by measuring object and image distances on an optical bench, and to show how the nature and size of the image change as the object moves.
- Finding the focal length by focusing the image of a distant object (class 10)
- Measuring image distance v for different object distances u and plotting u-v or 1/u-1/v graphs (class 11-12)
- Studying real, inverted and virtual, erect images and magnification
- Ray diagrams of reflection from a concave surface with optical pins
- Demonstrating uses such as shaving mirrors and reflectors
