When light travels in direction of optical centre of convex lens , it suffers very very slight deviation .....so from this, is it correct to conclude that such light rays/waves which are trevelling in direction of optical centre are actually travelling along the normal?explain

Expert Answer:

The optical centre of the lens is the centre of the sphere of which the lens is a small arc. Hence, we can say that light incident on the optical centre is actually incident on the centre of a circle. Any ray that is incident on the centre can be said to be incident perpendicular to it. So, the light rays pass through the optical centre undeviated.
