What term indicates the point where reflected light ray meet along an optical axis?
A focal point is the point where reflected light rays meet along an optical axis.
What is it called when light rays come together?
While the term light 'rays' is a 400 year old artifact and may give a misguided idea of what the visible part of the em wave spectrum is, the point at which the optical axis of a part of the incident plane of a light wave focused by a lens is called the FOCAL POINT of the lens. (It is not of course IN the lens).
What lens Has an optical axis?
If you are talking convex and concave, they both have an optical lens. Sorry if that doesn't help, but what do I know.
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.
Why is chromatic aberration more evident for some positions of the aperture?
The further the aperture is from the optical axis of the lens, the more to the side of the lens the incident light falls. The further the light falls from the optical axis, the greater the effects of chromatic aberration. This is because different wavelengths of light have different refractive indices (dispersion). Because of Snell's Law, n1sintheta1=n2sintheta2, the greater the angle of incidence, the more pronounced the effects of the difference in refractive indices. Spherical aberration further enhances the chromatic dispersion.

What is optical center of lens?
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.
What is the difference between the optical axis and the visual axis?
optical axis passing through centeres of cornea,lens to retina.visual axis is line passing through fixation point to fovea.
What is the center point of lens called?
axis or optical center
What is an optical axis?
optical axis
What is marginal rays?
Marginal rays are the light that passes through an optical system that is away from the optical axis.
How cardinal point of optical system located?
he points on the optical axis of a centered optical system that can be used to construct the image of an arbitrary point in space for objects in the paraxial region, which is the region around the axis of symmetry of the system where a point is represented by a point, a straight line by a straight line, and a plane by a plane.

The points on the optical axis OO' (see Figure 1) of a centered optical system that can be used to construct the image of an arbitrary point in space for objects in the paraxial region, which is the region around the axis of symmetry of the system where a point is represented by a point, a straight line by a straight line, and a plane by a plane.
Conjugated principal point?
The conjugated principal point is a term used in optics to refer to the point where the chief ray of a light ray bundle passes through the optical axis after being reflected or refracted by an optical system. It is also known as the focal point or image point. The position of the conjugated principal point depends on the characteristics and parameters of the optical system.
How light rays traveling parallel to the optical axis are bent after they pass through a convex lens?
After they pass through the lens, they converge, meaning that they come together at a specific point.
What is optic axis?
optical axis
