Question

Explain how refraction happens in concave and convex lens In the following situations 1. When a ray of light passes through the principal axis 2.when a ray of light passes through the principal focus 3.when a ray of light passes through the optic center. Plz reply fast.... it's urgent .... I'll mark the 1st to answer as brainliest....plzzzz

Answer 1

Answer:

Explanation:

Concave lens

1) After refraction from concave lens the ray appears to diverge from the principal focus located on the same side of the lens.

2)After refraction from concave lens, the ray will emerge parallel to principal axis.

3) After refraction from a concave lens the ray will emerge without any deviation.

Convex Lens

1)After refraction from a convex lens passes through the principal focus on the other side of the lens

2) After refraction the ray will emerge parallel to the principal axis.

3)  After refraction the ray will emerge without any deviation.
