When light strikes a convex lens the light beam?
Is bent towards a focal point.
What is a focus of the lens?
The distance at which the light rays bent by the lens (or mirror) converge into a coherent image.
How the focal length of a convex lens changes as the sides of the lens become less curved?
Longer focal lengths and less light rays are being bent. :) It's in the book.
The point where light waves appear to meet after being reflected by a mirror or lens?
Apex.
Why is a concave lens called a divergent lens?
A convex lens is wider at the edges than it is in the center. Therefore, it is a converging lens.

How does light travel through a carvex lens?
IF you meant a convex lens - light entering the lens is bent because it's passing from one medium to another - to converge at the focal point.
What is the difference between mirror and lenses?
Light passes through a lens, typically being bent by refraction. Light reflects off a mirror.
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.

The focal point

Why does a clear plain of white glass cant be used as lens?
By "White" I must assume you mean "Clear" otherwise the pane of glass would be opaque. A lens must have some curvature in order to focus light. A flat pane surface does not. The light may be bent on passing through the material, but will not be bent to a focal point, as would a lens.

What does the lens in an eye do?
Light from a single point of a distant object and light from a single point of a near object being brought to a focus by changing the curvature of the lens. The lens is a transparent, biconvex structure in the eye that, along with the cornea, helps to refract light to be focused on the retina.

Apex.
What happen when light passes through a regular lens?
1. - It is refracted (bent) relative to the source. 2. - The spectrum is separated, the amount depending on the thickness and curvature. 3. - A small part of the light is reflected off the lens, not passing through it. 4. - Assuming a 'perfect' regular (convex) lens, all light passing through the lens focuses at a single point in space, (focal point). 5. - Any image passing through the lens is reversed, equidistant from the focal point.
What is the focal lentgh of a lens?
It is a plane perpendicular to the lens at the focal distance from the lens. All parallel light entering the lens from a certain direction falls on a single point somewhere on this plane. Where the point of light falls depends on what angle the "wall" of light enters the lens.
