Curved Mirror Fun Model

Quick Answer: The Curved Mirror Fun Model is an optics demonstration mirror with a curved reflecting surface that stretches, squashes or flips a viewer’s reflection like a funfair mirror. It is used to show how concave and convex curvature changes the size and shape of an image.

Why Your Reflection Changes Shape

A flat mirror reflects every part of your face at the same angle, so the image is the same size and the right shape. Curve the mirror and that changes. Where the surface bulges outward (convex), reflected rays spread apart and the image looks smaller; where it curves inward (concave) and you stand close, the image looks larger. A fun mirror combines curvatures, so parts of the reflection grow and others shrink, producing tall-and-thin or short-and-wide versions of the viewer.

Standing further back from a concave region shows the next surprise: beyond the focal point the image flips upside down. Moving slowly towards and away from the mirror lets students find the distance at which the image turns over, a direct experience of the focal point long before they meet ray diagrams.

The model connects a fairground novelty with everyday devices. Convex mirrors are used as vehicle wing mirrors and road-junction safety mirrors because they give a wide field of view; concave mirrors appear in make-up and shaving mirrors, torch reflectors and solar cookers. Whether this model has one curvature, several or a flexible surface should be confirmed.

Demonstrations

• Exploring magnified, diminished and inverted images by walking towards the mirror
• Locating the approximate focal point of a concave region
• Linking to wing mirrors, safety mirrors and torch reflectors
• Open-day or science-fair exhibit that invites visitors to experiment

Specifications

Care & Handling

• Clean with a soft, lint-free cloth; many display mirrors have a plastic reflective face that scratches easily.
• Never use abrasive or solvent cleaners on the reflecting surface.
• Keep the mirror out of direct sunlight, because a concave surface can focus sunlight into a hot spot.
• Mount or stand the mirror securely so it cannot tip over.

Frequently Asked Questions

Why does a curved mirror make me look taller or shorter?

Different parts of the curved surface reflect light at different angles, so some parts of the image are magnified and others shrunk. Curvature running up and down stretches or squashes you vertically.

What is the difference between a concave and a convex mirror?

A concave mirror curves inward like the inside of a spoon and can magnify or invert images. A convex mirror bulges outward like the back of a spoon and always gives a smaller, upright image with a wide view.

Why does the image turn upside down when I step back?

Beyond the focal point of a concave mirror the reflected rays cross before reaching your eye, so the image is inverted. Inside the focal point the image is upright and magnified.

Where are curved mirrors used in real life?

Convex mirrors are used as vehicle wing mirrors and as safety mirrors at blind corners. Concave mirrors are used in make-up mirrors, torch reflectors, telescopes and solar cookers.

Is the curved mirror safe in sunlight?

Keep it out of direct sun. A concave mirror can concentrate sunlight into a hot spot that could scorch materials or harm eyes.

How should the mirror be cleaned?

Wipe it gently with a soft, lint-free cloth, slightly damp if needed. Avoid paper towels, abrasive powders and solvents, which scratch or cloud the reflecting surface.
