The focal point.

When rays of light converge? I think it is called the "refraction." :)
focal point ....would be preferred
refraction is more why it changes
They make the light rays converge to a point. Parallel rays converge at the focal point of the lens
The condenser-- when answering for a microscope!
Converging length is the point when two lines or rays of light converge.
If you want to know what will do this, a lens will, or a curved mirror
Rays which are parallel to the axis of the concave mirror will converge to the focal point.

Focus or the focal point.

It is the point at which all the light rays seem to converge in the case of convex mirror.
Real image
Hypermetertropia is refractive condition inwhich with accomodation relaxed light rays converge at a point behind d retina.
-- The distance from the center of the lens to the plane in which the rays converge is the 'focal length' of the lens. -- If the rays emanated from one point on an object, then rays from all the other points on the object do the same thing, and a real image is formed.
