Question

explain three rules of refraction of of light from convex lens with diagrams.

​

Answer 1

Answer:

In convex lens, the image is always formed at a point where at least two refracted light rays meet.

Rule 1: A ray of light which is originally parallel to the principal axis passes through the focus after refraction through the lens.

Rule 2: A ray of light passing through the optical centre of the convex lens does not bent after refraction but goes straight. Also, a ray of light going along the path of principal axis of a convex lens also goes straight and does not deviate.

Rule 3: When a ray of light passes through the focus of the convex lens then it becomes parallel to the principal axis after refraction through the lens.

Hope it helps :)

P.S- I'm sorry, I couldn't attach an image of the diagram, but it's easily available on Google. Check it out!!! :)
