Explain with diagram how a convex lens converges light rays?

Open in App

Solution

Explanation:
The incident rays travel through the lens and are refracted according to the rules of refraction.
When a beam of light rays parallel to one another and to the major axis of the convex lens passes through the lens, all of the rays converge at the same point F (focus) on the refracting side.
When Lightray passes through the optical center of a lens. After refraction from the convex lens, will emerge without any deflection
