Question

write one difference and one similarity between concave mirror and convex lens​

Answer 1

Answer:

                                  Similarity between the two

Concave mirror acts like a convex lens , quite frequently. This happens in the case that both of them converge their parallel rays. And they do so with the focal point, they converge rays to a focal point. Both of these have focal lengths that are positive. They furthermore, form similar images. Like images which have similar characteristics.

                                   Difference between the two

Their difference is that a concave mirror tends to converge the light from the focal point. However, in the case of convex lenses, the light is what converges to a point on the concerned convex lens.

Answer 2

Explanation:

Similarity - Both concave mirror and convex lens are converging..

Difference - Concave mirror cannot used in spectales(chashma) for view but convex lens is used in spectales for viewing.......
