After they pass through the lens, they converge, meaning that they come together at a specific point.
Light travelling through a concave lens will spread out. In most optical systems that use a concave lens, such as a telescope that needs to magnify the focal plane image, this is a desirable effect.
Converging. Tip: look at the pictures and read : http://en.wikipedia.org/wiki/Lens_(optics)
A convex lens can converge a beam of parallel rays to a point on the other side of the lens. It is useful for reflecting and transmitting light.
A camera, television, lap top, glasses, psp, claw machine.
A convex mirror produces a virtual image, because the principle light rays incident on the mirror surface from the object must pass through the focal point on the other side of the mirror (virtually), and so the image appears at a depth behind the mirror's surface. The three principle rays that form the focused image are: 1. The ray from the top of the object, parallel to the line passing through the center of the convex mirror, must pass through the focal point behind the mirror's surface. 2. The ray that passes from the top of the object and through the focal point in front of the mirror, comes through the mirror (virtually) parallel to the center line. 3. The ray that passes from the top of the object to the point where the surface of the mirror and the center line intersect, the reflection of which is traced back through the mirror's surface at the same angle as the reflected angle. The place behind the mirror where these rays intersect is the placement of the virtual image.
The rays are diffracted toward the center of the lens. This is the principal used in reading and magnifying glasses.

If passed through a convex lense, then yes the parallel rays will meet.
It is not necessary that a thinner convex lens have less optical power or a thicker lens has more optical power
Parallel rays after hitting the convex lens meet all at the focus of the lens.
An optical microscope or twlescope.
Double Convex
If you are talking convex and concave, they both have an optical lens. Sorry if that doesn't help, but what do I know.
Convex and concave lenses, and prisms.

Because a magnifying glass is made of of convex lens. It converses light rays and magnifies the objects seen through it.
Only if they enter the lens in the direction parallel to its axis.
