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.

∙ 15y agoA 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.

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.

State two types of meniscus shape?
Convex and concave or else they are also known as the upper meniscus and the lower meniscus
Would a graduated cylinder be read at the middle of a meniscus?
The answer depends on the liquid, or more specifically, how the surface tension in the liquid affects the meniscus. It should be the top of the meniscus for liquids such as mercury but the bottom for liquids such as water or alcohol.
What causes a meniscus to form?
Everyone has two menisci (pl. of meniscus) in your knee joint. It helps to cushion the knee joint. It can occasionally get torn and because it has a very poor blood supply, it generally won't heal without surgery.
Why does a concave meniscus form when water is in a graduated cylinder?
The force between glass and water are stronger than between water molecules
When water is in a container the surface of the water is curved this curve is call?
Meniscus is the curve at the surface of a liquid in a cylinder. It is caused by the adhesive and cohesive properties of water molecules. (Meniscus was incorrectly spelled in an earlier answer as "miniscus.")
Does meniscus always concave?
Do you mean is a meniscus always concave? If so, then no. For example, the meniscus of mercury is convex.
State two types of meniscus shape?
Convex and concave or else they are also known as the upper meniscus and the lower meniscus
Why does a meniscus occur?
It is because of the surface tension and cohesian of the molecules. It can be concave or convex.
What are the two shapes of meniscus called?
The surface is concave if the liquid is attracted to the container walls and convex if it is not
How does adhesion and cohesion results to the formation of a meniscus?
if adhesion>cohesion, concave meniscus from out if ahesion<cohesion, convex if adhesion=cohesion, flat surface
What is a curved surface on a liquid called?
A meniscus, but whether it has a positive curve or a negative one depends on whether it wets the glass.
What is the miniscus?
mEniscus is the curve or crescent of the surface on a liquid or substance and can be concave or convex. The meniscus should be taking in to account when a readings made to make precise measurements.
What is a meniscus why is it necessary to know about it when necessary liquids?
Meniscus is the curved surface of a liquid in a container; to measure correctly the volume in a graduated cylinder it is necessary to take into account the meniscus type, convex or concave.
What is meniscus Why is it necessary to know about it when measuring liquids?
Meniscus is the curved surface of a liquid in a container; to measure correctly the volume in a graduated cylinder it is necessary to take into account the meniscus type, convex or concave.
Is a jeweller's mirror concave or convex?
concave
Is a hen decagon concave or convex?
It can be convex or concave.
Difference between concave and convex in the dark?
concave is inward, convex is outward concave is inward, convex is outward
