A: The bottom of a concave meniscus. B: The top of a convex meniscus . In physics (particularly fluid statics ), the meniscus ( pl. : menisci , from Greek 'crescent') is the curve in the upper surface of a liquid close to the surface of the container or another object, produced by surface tension .
A lens with one convex and one concave side is convex-concave or meniscus. Convex-concave lenses are most commonly used in corrective lenses, since the shape minimizes some aberrations. For a biconvex or plano-convex lens in a lower-index medium, a collimated beam of light passing through the lens converges to a spot (a focus) behind
A meniscus (pl.: menisci or meniscuses) is a crescent-shaped fibrocartilaginous anatomical structure that, in contrast to an articular disc, only partly divides a joint cavity. [1] In humans , they are present in the knee , wrist , acromioclavicular , sternoclavicular , and temporomandibular joints ; [ 2 ] in other animals they may be present ...
In addition, the same attractive or repulsive effect can be observed between objects and the wall of the container. Once again there are two possibilities: the interface between the liquid and the container wall is either a concave or a convex meniscus. Buoyant objects will be attracted in the case of a concave meniscus and repelled for convex.
Meniscus may refer to: Meniscus (anatomy) , crescent-shaped fibrocartilaginous structure that partly divides a joint cavity Meniscus (liquid) , a curve in the upper surface of liquid contained in an object
Because of its high cohesion and low adhesion to the glass, mercury does not spread out to cover the bottom of the flask, and if enough is placed in the flask to cover the bottom, it exhibits a strongly convex meniscus, whereas the meniscus of water is concave.
A lens with two concave surfaces is biconcave (or just concave). If one of the surfaces is flat, the lens is plano-convex or plano-concave depending on the curvature of the other surface. A lens with one convex and one concave side is convex-concave or meniscus. Condensed matter physics
Since the force is perpendicular to the surface and acts towards the centre of the curvature, a liquid will rise when the surface is concave and depress when convex. [12] This was a mathematical explanation of the work published by James Jurin in 1719, [ 13 ] where he quantified a relationship between the maximum height taken by a liquid in a ...
