An image is called real if the light rays coming from a point(point on object) meet at a point after reflection or refraction. An image is virtual if the light rays do not actually meet after reflection or refraction. These rays appear to come from a point which is the point where we say virtual image is formed.
< the point where the two rays meet is called a vertex.
The point of intersection of light rays which have been intentionally manipulated to come to a point of converge, as we do with a parabolic reflecting surface, is called the focus. The parabolic reflector will (by virtue of mathematical principles and the physics of light) redirect parallel incoming rays back off its surface to the focus of the parabola. Links are provided.
This is the focal point, the point of focus.
the vertex
The point where light rays meet is called the focal point.
An image that is formed when light rays meet is called a real image. This type of image is formed when light rays converge to a point either on a screen or a surface.
The point where light rays converge after passing through a converging lens is called the focal point.
The location where light rays meet after reflecting from a concave mirror is called the focal point.
The focal point.Other answersWhen rays of light converge? I think it is called the "refraction." :)focal point ....would be preferredrefraction is more why it changes
Light rays that never meet are called parallel rays. These rays travel in the same direction without intersecting or converging at any point. This property makes them useful in physics and optics for analyzing how light behaves.
The point at which rays of light converge or appear to converge after being reflected or refracted by a mirror or lens is called the focal point.
The point where rays of light converge after passing through a lens is called the focal point. It is the point where the light rays come together, either in front of (converging lens) or behind (diverging lens) the lens.

The image formed when light rays actually meet is called a real image. This type of image can be projected onto a screen and is formed when the rays of light actually converge at a point.
A focal point is the point where reflected light rays meet along an optical axis.
