Light rays refracted by a concave lens?
spread out
How do light rays act when they pass through concave lens?
They spread out.
What will a concave lens cause light rays passed through it to 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.
What piece of glass could be used to focus parallel rays to a small spot of light?
Parralel light rays striking the concave lens in choice would diverge (spread apart).

How do light rays act when they pass through concave lens?
They spread out.
How do light rays react differently when they go through a concave lens and through a convex lens?
The photons are absorbed by electrons that they encounter, then re-radiated onward. If the convex lens is in a medium of lower refractive index, the light converges on its way through, and emerges still converging.
What happens to most of the light rays that strike the convex lens?
The, light rays reflect depending on the curature of the concave.
Why is convex lens also called converging lens?
because light rays meet at a single point and do not spread out.

Yes, this is a concave lens. It is also called a diverging lens because it causes light rays to spread out.
What happens to most of the light rays that strike a convex lens?
If the lens is convex, they will be diffracted and focused to a point, after which they will spread out. If it's concave, they will be diffracted so that they spread out without first concentrating.

Parralel light rays striking the concave lens in choice would diverge (spread apart).
What kind of lens which diverges light rays?
Concave lens would diverge the rays.
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.
