How are convex and concave lenses different from each other?
Convex lenses are thicker in the middle than at the edges. They cause light rays to converge. Concave lenses are thicker at the edges than they are in the middle. They cause light rays to spread out, or diverge.
Do thick concave lenses have longer or shorter focal lengths than thin concave lenses?
It have a shorter focal length because there is more time for the light rays to come together
What is the name given to a curved piece of glass which it used to bend light rays?
Concave or convex lenses
How does concave lens work?
Concave lenses work by refraction of light.
Describe what happen to parallel light rays hitting in a concave mirror?
describe what happens to parallel light rays when they hit a concave mirror
What are the use of concave?
Concave lenses are used todiverge rays of light.

What type of lens are need if you are nearsighted?
Lenses can correct vision problems by bending light rays before they reach the eye, in effect moving the focal point of the eye's lens so that it falls upon the retina and creates a clear image. Concave lenses cause light rays to converge and lengthen the focal point for the near sighted eye. Concave lenses are thinner in the middle and thicker on the edges and may be curved on one or both sides. Concave lenses cause light rays to diverge, or spread apart. :)

It have a shorter focal length because there is more time for the light rays to come together
What is the name given to a curved piece of glass which it used to bend light rays?
Concave or convex lenses
How are convex lenses and concave lenses the same?
They are not the same. Convex lens bulge outward, and concave lenses go in ward. Convex lenses focus light, and concave lenses spread light out.
Curved glass that bends light rays?
A lens is a curved glass that refracts or bends light rays. The two principal types of lenses are convex and concave.
What lenses refract light outward and are thinner in the middle?
its a concave lens(:
How does concave lens work?
Concave lenses work by refraction of light.
Do microscopes use concave or convex lenses?
They use convex lenses because they need to focus the light IN to the eye. Convex focuses in while concave spreads the light out. So, they use convex lenses.
Describe what happen to parallel light rays hitting in a concave mirror?

Is the concave lens bends light rays toward the center?
concave lens bends light rays away from the center
