Question

Why the ray passing through optical centre of a lens remains undeviated?

Answer 1

Actually the same happens when a ray of light passes through optical centre the perpendicular distance between extended incident ray and extended emergent ray is negligible so... we can say that the ray which through the optical centre is undeviate. I give you the answer please mark me braniliest

Answer 2

Answer:

1. The portion of a lens near the optical centre is like a very thin slab of glass.

2. Hence, the ray of light passing through the optical centre of a lens remains undeviated.

Explanation:

Optical Centre :

1. The point inside a lens on the principle axis, through which light rays pass without changing their path is called the optical centre of a lens.

2. It is denoted by O.
