1. Plane Mirror
-
Flat surface (like a bathroom mirror).
-
Image formed: same size as the object, upright, appears behind the mirror.
-
Everyday use: mirrors at home, shops, cars (inside rear-view mirror).
👉 Think: "what you see is what you get."
2. Concave Mirror (curves inward like a cave 🕳️)
-
Shaped like the inside of a spoon.
-
Can magnify or flip an image depending on how far the object is:
-
Close to mirror → big, upright image (like a makeup/shaving mirror).
-
Far away → smaller, inverted image (used in telescopes, headlights).
-
-
Focuses light at a point in front of the mirror.
👉 Concave = "caves in" → can make things look bigger.
3. Convex Mirror (curves outward like the back of a spoon 🥄)
-
Surface bulges out.
-
Always makes images that are smaller, upright, and wider view.
-
Used for security mirrors in shops, or side mirrors on vehicles.
-
Spreads light outward.
👉 Convex = "bulges out" → helps you see more area.
Quick Comparison Table
| Mirror Type | Shape | Image | Common Use |
|---|---|---|---|
| Plane | Flat | Same size, upright | Household mirrors |
| Concave | Inward curve | Big & upright (close), small & inverted (far) | Makeup mirrors, telescopes |
| Convex | Outward curve | Small, upright, wide view | Car side mirrors, shop mirrors |
✨ In short:
-
Plane = normal mirror, true size.
-
Concave = can magnify (close up).
-
Convex = always smaller, shows more area.
