Rays of light incident on lens and parallel to the principal axis of the lens converge?

This depends on the type of lens. If it is a convex lens then they converge at the focus on the other side of the lens. If it is a concave lens, then they diverge and appear to be coming from the focus present on the same side of the lens as the incident ray.

How does the lens change to focus on objects that are close?
Okay when the light waves are coming from far away, they are probably almost parallel to each other so they easily converge on the retina due to the lens. Now for nearer objects the light does not easily converge as they are not parallel and diverge away from each other as they move forward. So to converge them on the retina the lens broadens/thickens. Then the light rays can easily be converged. This phenomenon is called "accommodation".
What is incoming solar radiation called?
incident ray i think
Convex lens is thicker than?
The top of the convex lens is thicker than the bottom.
Reflection of light in all directions?
When light falls on a plane polished surface,it changes its direction.This is called reflection of light.
What rock has parallel bands of dark and light mineral grains?
It is a sedimentary rock
Rays of light incident on a lens anb parallel to the principal axis of the lens converge?
They converge in the focus of the lens. It can be, of course, real or imaginary (it depends on if the lens is concave or convex, respectively).
What happens when rays of light incident on a lens and parallel to the principal axis of the lens converge?
-- 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.
What do lenses do to light rays?
They make the light rays converge to a point. Parallel rays converge at the focal point of the lens
What do converging lenses do to light rays?
They make the light rays converge to a point. Parallel rays converge at the focal point of the lens
What is the principal focus of convex mirror?
It is the point at which all the light rays seem to converge in the case of convex mirror.
Why is the ray of light parallel to the principal axis passes through the focus?
Well this only occurs if the lens is parabolic. It is just a fundamental feature of a parabola to reflected an incident ray parallel to the principal axis through the focal point. That is why lenses etc are parabolic. I dont know if this answers your question (it probably doesnt) but oh well...
Why wont a piece of ordinary window converge or diverge light rays?
"Ordinary window" is a sheet of glass or perspex where the two faces are parallel. Light will be refracted at each face, but for light rays incident parallel to eachother, such as sunlight, they will br refracted through equal angles, hence remaining parallel. Some older glass windows which have undulating surfaces can produce effects such as rainbow patterns on walls and floors due to two non-parallel faces acting like a prism.
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.
Does a plane mirror converge a parallel beam of light?
No. The angle of incidence will equal the angle of reflection. No convergence will take place.
How do convex lenses bend light rays?
convex lenses bend light through refraction 1) a light ray that is parallel to the principal axis is refracted through the principal focus F. 2) A light ray passing through the principal focus F' is refracted parallel to the principal axis 3) a light ray passing through the lens' midpoint travels straight on -K14

Why does a light ray incident on a rectangular glass slab immersed in any medium emerges parallel to itself?
The glass slab is rectangular and both sides of the glass slab have the same medium. The light refracts in such a way that incident and emergent rays are parallel.
