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.
When light changes direction as it passes through a boundary.
a beam of light can be seen if it passes through reflective material.
Converging. Tip: look at the pictures and read : http://en.wikipedia.org/wiki/Lens_(optics)

Transmission
When light passes through a concave lens, it diverges or spreads out. This results in the formation of a virtual and upright image. On the other hand, when light passes through a convex lens, it converges or comes together. This leads to the formation of a real and inverted image.
No it do not bend.
When light passes through a concave lens, it diverges or spreads out. This causes the light rays to bend away from each other. In contrast, when light goes through a convex lens, it converges or comes together at a focal point. This causes the light rays to bend towards each other.
When a light ray passes through a focal point of a convex mirror, it will reflect parallel to the principal axis. This is because the reflected ray follows the law of reflection, where the incident angle is equal to the reflection angle.
It happens by the refraction of light.
The lens is a convex shape which allows it to concentrate and magnify light which passes through it.
sh@@ happens
The light refracts or bend .
An incident ray that passes through the vertex of a convex lens will continue in a straight line without being refracted. This is because the lens is thinnest at the vertex and has minimal effect on the path of light passing through this point.
it refracts
It is redirected as it passes through a medium
