Rays do not reflect or refract at the optic center of a lens because, at this point, the angle of incidence is effectively zero. This means that the incoming rays travel parallel to the lens's optical axis, and as a result, they continue in a straight path without bending or changing direction. The optic center acts as a point where the lens's curvature does not cause any deviation in the light's path. Thus, light passes through without experiencing reflection or refraction.
Light rays reflect when they hit a concave mirror. The parallel rays of light converge at the focal point after reflection.
X-rays neither refract nor reflect light. They interact differently with matter compared to visible light, as they are able to pass through soft tissues like skin and muscle but are absorbed by denser materials like bones.
A convex mirror has the same type of curve as the bottom of a spoon - it bulges out. Mirrors reflect.
optic centre is the geometrical centre of the lens the rays of light passing through this point emerges in the same direction without bending.

A concave lens causes light rays passing through it to diverge because it is thinner at the center than at the edges. This shape causes the light rays to refract away from the optic axis, resulting in divergence.
The sun's rays are scattered by gases in the atmosphere. They also refract through water droplets in the lower atmosphere to create rainbows.
Pennies reflect light. When light hits a penny, its surface reflects the light rays in various directions, giving the penny its shiny appearance. Refraction occurs when light passes from one medium to another, causing the light rays to change direction.
When rays of light come together and are focused in a specific direction, they form a beam of light. This beam can travel in a straight line until it hits a surface where it can reflect, refract, or be absorbed.
When two rays of light intersect, they can either reflect, refract, or pass through each other depending on the angle at which they meet and the properties of the materials they are traveling through.
A diverging lens causes light rays to diverge (spread apart) after passing through it. This lens is thinner in the middle than at the edges, causing light rays to refract away from the optic axis. This results in the formation of virtual images that are always upright and smaller than the object.
By convex lens, rays fallen would be definitely converged hence named as converging lens. If rays fall parallel to the principal axis after refraction they would be converged at a point known to be the principal focus of the lens. If rays go in diverging state as the source is in between its F and O, optic centre then they would appear to come from the same side and so we get a virtual enlarged image. This is what a palmologist does with a lens to read the lines on the palm. Optic centre is the point on the lens through which as rays pass then it goes unrefracted or undeviated.
