In optics, a thin lens is a lens with a thickness (distance along the optical axis between the two surfaces of the lens) that is negligible compared to the focal length of the lens. Lenses whose thickness is not negligible are sometimes called thick lenses.

What is a lens that is thin in the middle and thick at the edge is it convex?

A lens that is thin in the middle and thick at the edges is convex. This shape causes light rays passing through the lens to converge and focus at a point, making it a converging lens.


What is a difference between a concave and convex lens?

A concave lens is a lens in which the ends are thicker than the middle, rather shaped like this ---> )( A convex lens is a lens in which the ends are thinner than the middle, shaped like the following ---> ()


Will the focal length be greater in a thick or thin convex lens?

The focal length will be greater in a thin convex lens compared to a thick convex lens. Thinner lenses have less curvature, causing light rays to converge more gradually and thus increasing the focal length.


What lens is thick in the middle and thin at the edge?

A converging lens or a convex lens is thick in the middle and thin at the edges. It causes light rays to converge at a focal point, which makes it useful for focusing light in optical systems like cameras and telescopes.


What kind of lens is thick in the middle?

A converging lens, also known as a convex lens, is typically thick in the middle and causes light rays to converge to a focal point.


What is the main difference between how convex and concave lenses affect light?

Concave lenses are thicker at the edges then at the middle. A Convex lens is a lens that is thicker in the center than at its edges.


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

A convex lens.


What is the difference between the virtual image formed by a convex lens and a concave lens?

The difference is that when virtual image is formed by the concave mirror...it is larger than its original size..but when it is formed by the convex mirror..it is smaller than the original size....


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

A convex lens.


Difference between convex and concave lens?

The difference between concave and convex is that convex lenses are the type of lens that make images bigger, while concave make images smaller. Still confused, maybe this will help. When you think of concave think of a cave, how you can see a small image at the end of the cave, while convex is the opposite.


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.
