Curves inward, like the inside of a spoon.
Curves outward, like the back of a spoon.
Enlarged up close, inverted farther away — torch reflectors, dentists' mirrors.
Always smaller and erect — vehicle side-mirrors, for a wider view.
Parallel rays stay parallel.
Rays converge — concentrating sunlight enough to burn paper.
Rays spread out, diverging.
Thicker in the middle — like a curved water drop that magnifies text beneath it.
Thicker at the edges than in the middle.
Enlarged up close, inverted and smaller farther away — can focus sunlight to burn paper.
Always erect and smaller — used with convex lenses in eyeglasses and telescopes.
Same size, erect — everyday mirrors.
Enlarged near, inverted far — torch reflectors.
Always smaller, erect — safety mirrors.
Curves inward / curves outward.
Light hitting a mirror / bouncing back.
The perpendicular line at the point of reflection.
Angles the rays make with the normal.
Transparent material that bends light through it.
Thicker in the middle; converges light.
Thicker at the edges; diverges light.
Left-right flip seen in a mirror image.
