.If a ray of light passes along the
principal axis of a convex lens.it
O Retracės its path
O Deviates by 30
O This cannot happen
O
Passes through the lens undeviated​

Answer 1

Answer:

A ray of light passing through the optical center suffers no refraction, that is, it passes undeviated. This is because, when it passes through the optical center, it is perpendicular to the curved surface of the lens. Hence, the angle of incidence is zero and therefore the angle of refraction is also zero.

Hence, the statement is true.

Answer 2

Passes through the lens undeviated​ is the correct answer for the given question.

If a ray of light asses along the  principal axis of a convex lens shows no change in its speed or angle of movement.

A Lens with a convex shape. Light rays passing through the lens are pushed closer together (they converge). A converging lens is one that is convex. When parallel light beams travel through a convex lens, the refracted rays converge at the main focus.

After refraction from a convex lens, a beam of light passing through a primary focus appears parallel to the principal axis. After refraction, a ray of light growing to match at the primary focus of a concave lens develops parallel to the principal axis.
