✓
Answer
Concave lens:
- A concave lens has its surfaces curved inwards.
- It is thicker at the edges than in the middle.
- It can form only a virtual image.
- It can form only a diminished image.
Convex lens:
- A convex lens has its surfaces puffed up outwards.
- It is thicker in the middle than at the edges.
