Question

difference between concave and convex lens​

Answer 1

Answer:

concave, bulged surface inside and in convex bulged out side

Explanation:

very simple just detect difference by seeing the images

Answer 2

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.
