What causes light rays passing through it to refract?
double concave lens
What happend to rays of light when they are refracted by a convex lens?
Now suppose that the rays of light are traveling through the focal point on the way to the lens. These rays of light will refract when they enter the lens and refract when they leave the lens. As the light rays enter into the more dense lens material, they refract towards the normal; and as they exit into the less dense air, they refract away from the normal. These specific rays will exit the lens traveling parallel to the principal axis.
What causes light rays to refract?
light travels in straight path and when speed of medium in which light travels change then it refract due to change in speed light rays bend and refract
What lenses refract light rays in toward a central point?
Convex lenses refract light rays in towards a central point. =()>
Why are convex lens thicker in the middle than at the edge?
A lens works by delaying light. When light rays encounter a lens, they refract the rays in the direction of the slower area, so a lens that is convex - thinker in the middle and thin on the edges - will bend all the light passing through it to come together. We design the lenses as thicker or thinner to deflect the light in the direction we want it to go.

What causes light to refract when it hits a piece of glass?
the light rays hit the piece of glass and the surface of the glass causes it to refract

Parallel light rays that pass through a convex lens are?
Converging. Tip: look at the pictures and read : http://en.wikipedia.org/wiki/Lens_(optics)

What happens to light rays as they pass through lenses?
well it encounters the lens and adjusts thickness to focus
Causes light rays passing through it to meet at a focal point?
A lens.
What causes light rays passing through it to diverge?
double concave lens
Do X-rays refract or reflect light?
yes they do
Is a lens that is thicker at the edges than in the middle a concave lens?
Yes, this is a concave lens. It is also called a diverging lens because it causes light rays to spread out.
