Question

The difference between a convex lens and a concave lens are

Answer 1

Explanation:

convex lens:

convex lens diffracted all the rays in different directions.

focal length is positive.

Form real and inverted image.

Concave lens:

concave lens converges all the rays at one point.

focal length is negative.

form virtual, erect and diminished image.

Answer 2

here is your answer mate ✅✅

Concave lens:

1) It has both surfaces curving inwards.

2) It is thicker at edges and thinner at middle.

3) It diverges the light coming towards it.

4) Its focal length is negative.

5) It always produces a virtual image.

Convex lens:

1) It has both surfaces curving outwards.

2) It is thicker at middle and thinner at the edges.

3) It converges the light coming towards it.

4) Its focal length is positive.

5) It always produces a real image and forms a virtual image only when the object is between the focus and optical centre.
