Question

State two differences between a convex and a concave lens. ​

Answer 1

Answer:

CONVEX:

• A convex lens is thicker in the middle and thinner at the edge
• Convex lens can form both real and virtual images.

CONCAVE:

• A concave lens is thinner in the middle and thicker at the edges.
• Concave lens always forms a virtual image.It can form magnified image.

Answer 2

concave lens is converging lens and convex lens is diverging lens.

concave lens have middle part thick whereas convex has thin.

concave have edge thin and convex has thick edges.

concave lens use in correction of hypermetropic eyes and convex for myopic eyes.
