What is a concave meniscus and a convex meniscus?

Answer 1

Concave and convex lenses are curved lenses that bend light in a predictable manner depending on their radius of curvature and index of refraction. A concave lens bend inwards and a convex lens bends outwards.

Answer 2

A meniscus is the curved surface of a liquid. A concave meniscus curves downwards, with the middle being lower than the sides A convex meniscus curves upwards, with the middle being higher than the sides.

Answer 3

Lenses

Concave Lenses Convex Lenses

Convex lenses are thicker in the middle then the edges and concave are thicker at the edges then the middle. When light travels through lenses, refraction occurs. The light bends either outward or inward, it depends on the lens.

The lens of your eye is a double convex lens. Its job is to focus the image on the retina of the eye. If one is farsighted, the lens in the eye causes the focus to be behind the retina.

Answer 4

A concave meniscus curves downward at the edges, creating a higher surface tension in the center compared to the edges. A convex meniscus curves upward at the edges, creating a lower surface tension in the center compared to the edges. These differences in curvature play a role in phenomena such as capillary action and the behavior of liquids in containers.

Answer 5

The surface tension of the liquid determines which of these happens. The surface tension depends on the surface energies of both the liquid and the container wall material.
