Product Code : SCL-LAO-11296
The Physics Demonstration Convex Mirror is an educational optical element used to demonstrate divergent reflection, virtual image formation and wide-field viewing. It helps students and teachers trace reflected rays, identify the virtual focus and compare convex-mirror behaviour with plane and concave mirrors.
Product Description
A convex mirror has an outward-curving reflective surface. Parallel incident rays reflect outward and appear to originate from a virtual principal focus behind the mirror. For a real object placed in front of the mirror, the resulting image is normally virtual, upright and diminished.
The mirror can be used in a ray-tracing arrangement, demonstration stand or compatible optical-bench holder. Its diameter, focal length, radius of curvature, substrate material, reflective coating and mounting configuration must be confirmed from the current product specification.
Key Features
- Diverging reflection: Demonstrates how parallel rays spread after reflection from an outward-curved surface.
- Virtual-focus study: Supports backward extension of reflected rays to locate the apparent principal focus.
- Diminished image formation: Shows the upright, reduced virtual image associated with convex mirrors.
- Wide field of view: Helps explain why convex mirrors display a broader scene than similarly sized plane mirrors.
- Ray-tracing compatibility: Can be used with a ray box or another suitable narrow-beam source.
- Reusable optics component: Suitable for repeated classroom demonstrations and supervised laboratory practicals.
- No electrical requirement: The mirror itself requires no power; a separate light source may be used.

How to Use the Physics Demonstration Convex Mirror
- Inspect and clean the reflective surface before use.
- Secure the mirror in a compatible stand or optical holder.
- Align its principal axis with the ray source or demonstration object.
- Direct parallel or narrow rays toward the convex surface.
- Trace the reflected rays as they diverge from the mirror.
- Extend the reflected rays backward to locate the virtual focus.
- Place an object in front of the mirror and observe the image position, orientation and size.
- Compare the observations with a convex-mirror ray diagram.
Safety note: Handle the mirror by its frame or edges. Do not use chipped or cracked components, and never direct laser beams or concentrated light toward the eyes.
Care & Maintenance
- Remove loose dust with a soft brush or optical cleaning cloth.
- Do not use abrasive cleaners on the reflective surface.
- Avoid touching the mirror face with bare fingers.
- Store the mirror in padded, dry packaging with the reflective face protected.

Frequently Asked Questions
What is a Physics Demonstration Convex Mirror used for?
It is used to demonstrate divergent reflection, virtual focus, diminished image formation and wide-field viewing.
What type of image does a convex mirror form?
For a real object, a convex mirror normally forms a virtual, upright and diminished image behind the reflective surface.
Why is a convex mirror called a diverging mirror?
Parallel incident rays spread apart after reflection and appear to originate from a virtual focal point behind the mirror.
What is the focal length of this mirror?
The focal length is not published for this exact product. Confirm its nominal value and tolerance before procurement.
Does the mirror include a holder?
A holder or stand has not been confirmed. Request an itemized packing list and mounting dimensions.
Can it be used on an optical bench?
Yes, provided the mirror frame and stem dimensions match the intended optical-bench carrier or holder.
Request the confirmed diameter, focal length, coating and holder configuration, or explore the Light and Optics equipment category for related educational mirrors.
