Convex Mirror 5cm Glass

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.

Show you more. Because it spreads light outward, it takes in a much wider view than a flat mirror of the same size - which is why they are used on cars, in shop corners and at blind driveways.

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.

Yes. A convex mirror spreads light rather than focusing it, so unlike the concave one it cannot bring sunlight to a burning point. Do not use it to flash sunlight into anyone's eyes, but there is no heat risk.

No, it is the mirror alone. Prop it against a block or hold it in a clamp on the bench.
