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
Curiously enough, this is true by construction. A straight line (also known as a geodesic) is defined as the trajectory of light, so light itself travels in straight rays by definition. Such straight lines are also the lines of least distance.
You can get a feeling why this is so by considering a light ray. Imagine it traveling from some point A to some other point B. Now since the straight line is the shortest way from A to B, light must travel this path because otherwise it would be possible to take the shortest way yourself (at a speed slower than the speed of light) and arrive at B before light, thus traveling faster than light itself!
when the ligt ray passes through optical centre it does not refract because when the ligt rays passes through other part of lens it converge or diverge so we assume that the optical centre has no power converge or diverge so the ray does not refract through he optical centre
"angle incidence=angle reflection" If your angle of incidence is not skewed, your angle of reflection will also remain unaltered.
It's a tricky question, and I am answering from the point of view of an interested layman, not a physicist. Light travels on a straight path through space. The interesting reality is that the space around gravitational fields bends.Light travels in a straight path through bent space. Also, light can be transmitted through optical fibers in communications systems, and the light follows the fiber through whatever bends are put into it.
Visible light.
Transparent objects allow light to pass through them in straight lines
The light used in optical fibres is either visible or infra red like my super whizzie broadband....
When it passes through optical centre.
This physical phenomenon is called refraction.
The optical center of the lens is a point on the axis of a lens is the point where any ray passing through this point, the incident part and the emergent part are parallel. It is important for the proper refraction of light.
Nothing. It continues to travel in a straight line.
Optical bench is used for the moving the light in straight away from the photocell.

optic centre is the geometrical centre of the lens the rays of light passing through this point emerges in the same direction without bending.
Marginal rays are the light that passes through an optical system that is away from the optical axis.

Rays are used to model the propagation of light through an optical system
isn't that what optical light is? like you know on certain fake Christmas trees ,, they have those lights in them that change colors; not tree lights but optical lights?
