Why ray does not refract when it passes through optical centre?

It does. But when the ray arrives perpendicular to the boundary,
the angle of incidence and the angle of refraction are both zero,
so its direction doesn't change.

What is meant by Tana position?
if the axial line of the magnet passes through centre of the deflection magnetometer it is called as tana position
What are the three laws governing light passing through a converging lens?
Any incident ray traveling parallel to the principal axis of a converging lens will refract through the lens and travel through the focal point on the opposite side of the lens.Any incident ray traveling through the focal point on the way to the lens will refract through the lens and travel parallel to the principal axis.An incident ray that passes through the center of the lens will in effect continue in the same direction that it had when it entered the lens.
What Lines of latitude across Kenya?
Many lines of latitude pass through Kenya. Perhaps the most notable is the equator.
Do lenses reflect or refract light?
Light refracts when it passes across the boundary of two media having different optical densities (refractive indexes). If the light stated in the question had done this, then it is refracted.
Which line of longitude passes through middle of India?
Longitude passing Through Centre of India is at 82 and a 1/2 degree east.
When a ray of light passing through a point in a lens does not undergo deviation?
When it passes through optical centre.
Do all lenses refract the light passes through them?
yes
Why light ray move straight through optical center?
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
Does light only refract when it passes through a translucent object?
Light refracts when it passes from one medium into another one with a differentrefractive index.If transparent objects didn't refract light, then eyeglasses wouldn't work.
What is marginal rays?
Marginal rays are the light that passes through an optical system that is away from the optical axis.
What is the name for a chord that passes through the center of a circle?
The chord that passes through the centre is the biggest chord in a circle and it is the diameter.
Why is it possible to simplify the number of actual refractions in a lens down to one refraction at a central line through the optical centre?
There are a few reasons why it is possible to simplify the number of actual refractions in a lens down to one refraction at a central line through the optical centre. One reason is that when light passes through a lens, the lens refracts the light in such a way that the light is brought to a focus. The amount of refraction that occurs depends on the curvature of the lens and the index of refraction of the lens material. However, no matter how curved the lens is, the amount of refraction is always the same at the optical centre of the lens. This is because the optical centre is the point on the lens where the light rays passing through the lens are parallel to the principal axis of the lens. Another reason why it is possible to simplify the number of actual refractions in a lens down to one refraction at a central line through the optical centre is that when a lens is rotated about its optical axis, the image formed by the lens does not rotate. This is because the optical centre of a lens is invariant with respect to rotation. This means that it is not necessary to take into account the actual refractions that occur at different points on the lens when calculating the image formation by the lens.
What is a chord that passes through the centre of the circle called?
It is the circle's diameter
What is the distance that passes through the centre of a circle called?
It is the diameter of the circle.
Does the axis pass through the center of the Earth?
Yes, the axis of the Earth passes through its centre.
Does clear glass refract light?
Clear glass does refract light when light passes from another medium like water to clear glass. But there is an exception. If the ray of light were to pass through water and hit the clear glass straight or at 90 Degrees to the surface, then clear glass does not refract the light.
Light refracts when light passes from one?
Some kind of lens or a change in a substance: the surface of a pond, through a prism, through glass... all of these may refract light.
