A concave glass mirror, 5cm across, sold on its own

Quality curved glass mirror, 50mm diameter.

A concave mirror curves inward and reflects light towards a single focal point. That is why it is the shape used in makeup mirrors, where the image comes out magnified, and in reflecting telescopes, car headlights, spotlights and torches, where the job is to gather light and throw it forward.

The supplier lists the focal length as 100mm. They print it with a minus sign, which is a sign convention rather than a physical property - it does not change how the mirror behaves. If the sign matters for your senior classes, ask us and we will get it confirmed.

Glass rather than polished plastic, because a curved plastic mirror distorts in ways that have nothing to do with the curve you are trying to teach.

Sold individually. Most lessons want a concave and a convex side by side so students can compare, so order one of each.

FAQs

One mirror. The concave and the convex are separate lines - buy one of each if you want students to compare them, which is how the lesson usually works.
Focus. A flat mirror sends parallel light back parallel. A concave one brings it to a point, which is why it magnifies close objects and why telescopes and headlights use the shape.
That depends on how far the object is from the mirror, which is the whole investigation. Move a pencil towards and away from the surface and watch what happens to its size and which way up it is.
Treat it like a magnifying glass. A concave mirror focuses sunlight to a hot point that can scorch paper or skin, so outdoor use needs supervision and it should never be aimed at anyone.
No, it is the mirror alone. Prop it against a block or hold it in a clamp on the bench.
