What are two basic kinds of lenses?

Two basic kinds of lenses are converging lenses, which focus light rays to a point, and diverging lenses, which spread out light rays. Converging lenses are thick in the center and thin at the edges, while diverging lenses are thin in the center and thick at the edges.


What is a lens has a center that is thicker than its edges?

A convex lens.

What are the differences between a thick lens and a thin lens in terms of their optical properties and applications?

Thick lenses have more curvature and can focus light at different points, while thin lenses have less curvature and focus light at a single point. Thick lenses are used in cameras and microscopes for magnification, while thin lenses are used in eyeglasses for vision correction.


Do thick concave lenses have longer or shorter focal lengths than thin concave lenses?

Thick concave lenses have shorter focal lengths than thin concave lenses. This is due to the increased curvature of the lens surfaces in thick lenses, which causes light rays to converge more quickly to a focal point.


Which lens is THIN in the middle and thiCK At the edges?

A convex lens.


What is a line drawn around the edges of a table or cell?

That's commonly called a border. Borders can be as thin as one pixel, or as thick as you want !


What is a lens that is thicker at the edges than the middle?

Concave. The opposite- thick in middle, thin at edges- is convex.

What type of lens is used in spectacles to correct long sightedness?

Convex lenses, which magnify, correct hyperopia. Below, is a previous wiki answer to this question in detail.Convex are thicker in the middle and thin out at the edges. These lenses magnify and are used for reading glasses and to correct long-sightedness (hyperopia).Concave lenses are thin in the middle and thick towards the edges. These lenses shrink things and are used to correct short-sightedness (myopia).A good example of this is to take a spoon and look at your reflection in it. Looking at the concave side of the spoon (the front) will make you look smaller, looking at the convex side of the spoon (the back) will make you look biggeRead more: Which_type_of_lens_magnifies_-_convex_or_concave

Whats the difference between thick and thin lens?

A thick lens has varying thickness across its surface, which affects how light is refracted. A thin lens is assumed to have a uniform thickness, simplifying calculations in optics. Thick lenses can produce more complex optical effects compared to thin lenses.
