Why does a meniscus occur?
It is because of the surface tension and cohesian of the molecules. It can be concave or convex.
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 type of lens always produces smaller images?
Concave D. Diverging
How are concave lens and convex lens different?
The convex lens bulges out at the center, while the concave lens bulges in at the center. The convex lens magnifies, while the concave lens reduces.
When the reflection of an object is seen in a concave mirror the image will?
always be real.
State two types of meniscus shape?
Convex and concave or else they are also known as the upper meniscus and the lower meniscus
How is a meniscus used in measuring?
As the diameter of the container decreases, the meniscus becomes more pronounced. The meniscus may be convex (curving upward) or concave (curving downward). Most of the time you will find that the meniscus is concave. The most notable exception is the meniscus that forms from mercury. When taking measurement readings it is important that the reading is done properly. The following rules must be adhered to: I. Read the meniscus at eye level. Do not read the meniscus from above or below eye level. Significant measurement errors may occur II. Read the bottom of a concave meniscus and the top of a convex meniscus.
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.

if adhesion>cohesion, concave meniscus from out if ahesion<cohesion, convex if adhesion=cohesion, flat surface
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.
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 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
What is a meniscus why it necessary to know about it when measuring liquids?
The meniscus is the concave line of liquid that forms in a graduated cylinder (measuring volume) due to that liquid's adhesion (the tendency to want to stick to other things). When measuring a liquid's volume in a graduated cylinder, you read the volume from the bottom of the meniscus. Therefore, the meniscus does not measure anything, it is where you measure a liquid's volume from.
Is a triangle concave?
Yes, a triangle is always concave. * * * * * How wrong can you get! A triangle is always convex and NEVER concave.
Why should volume measures always be placed on a level surface?
When measuring volumes you should always measure from the bottom of the meniscus - the surface of a volume of liquid always has a slight curve called the 'meniscus'. Since the surface of any still volume of water is not flat (it is always either a convex or concave curve), it should be measured on a level surface at eye level - bend your knees until your eyes are level with the miniscus to measure accurately.
