as per the law of reflection angle incidence=angle reflection and angle is measured with respect to normal so when it passes from centre its normal,its incident ray, its reflected ray becomes in straight line
No, light is not always bent toward the optical center of a lens. Light rays passing through a lens can be bent towards or away from the optical center depending on the shape and curvature of the lens. This bending of light is what allows lenses to focus light and form images.
Light beams falling along the optical axis of a concave lens do not refract because they are already passing through the center of curvature of the lens, where the refractive index and hence the angle of refraction is zero. This means that the light beams travel straight through without being bent.
Light passing through the optical center of a lens does not deviate in direction.
The optical center of a lens is the physical center point of the lens where light rays passing through it converge without any deviation. This point is important in determining the optical axis of the lens and is often used as a reference point in lens designs and calculations.
A lens with an optical axis is symmetrically designed, meaning that the center of the lens coincides with the optical axis. This axis passes through the center of curvature, allowing light to pass through without significant deviation. Lenses that are not symmetrical may not have a distinct optical axis.

The optical center of a lens is a point on the lens axis where light passing through the lens does not deviate, regardless of the angle of incidence. It is often used as a reference point for optical calculations and design. The optical center is typically at the geometric center of a lens with a symmetrical shape.

This physical phenomenon is called refraction.

Nothing. It continues to travel in a straight line.
Optical bench is used for the moving the light in straight away from the photocell.

This axis passes through the center of curvature, allowing light to pass through without significant deviation. Lenses that are not symmetrical may not have a distinct optical axis.
The optical center of the lens is important because it is the point where light rays passing through the lens do not deviate or change direction. This makes it a reference point for designing and aligning optical systems to ensure accurate focusing and image quality.
When light passes through the optical center of a lens, it does not refract because the optical center is the point from which light rays are believed to pass undeviated. This means that the angles of incidence and refraction are both zero, resulting in no bending of the light ray.
