Concave Lens vs Convex Lens — Comparison Table
| Basis | Concave Lens | Convex Lens |
|---|---|---|
| Shape | Curved inward (thinner at center) | Curved outward (thicker at center) |
| Type of lens | Diverging lens | Converging lens |
| Image formed | Virtual, erect, diminished | Real or virtual (depends on object position) |
| Focal length | Negative | Positive |
| Uses | Magnifying glass for myopia (short-sightedness) | Magnifying glass for hyperopia (long-sightedness) |
Key Points
- Concave lens diverges light rays; convex lens converges light rays
- Concave lens always forms virtual, erect, smaller images
- Convex lens can form both real and virtual images depending on object distance
- Convex lenses are used in cameras and microscopes; concave in corrective lenses
