You do not see a meniscus in Diagram C, as the liquid surface is flat and level with no curvature at the edges.
You measure from the bottom curve of the meniscus.
Do you mean is a meniscus always concave? If so, then no. For example, the meniscus of mercury is convex.
No, the meniscus is not the same height for every liquid. The curvature of the meniscus depends on the cohesive and adhesive forces between the liquid molecules and the container surface. Different liquids will have different interactions with the container, leading to varying meniscus heights.
A graduated cylinder or a buret must be read at the meniscus, which is the curved surface of a liquid in a container. Reading at the bottom of the meniscus helps to minimize parallax error and ensures a more accurate measurement.
To measure the volume of a liquid accurately, it is important to read the meniscus at eye level.
meniscus is when you fill the beaker upwith liquid. when yo go down to look at the beaker with eye level, you see a dip. that's the meniscus. -used in science

Meniscus
The name of the curve is the "meniscus".
That is called the 'Meniscus.'
If the colored liquid is opaque (you can't see through it) you can't see the bottom of the meniscus. If the liquid is like mercury, you can't see through it but it doesn't make any difference because the meniscus is reverse from that of water. You read the top.
A meniscus, but whether it has a positive curve or a negative one depends on whether it wets the glass.

Water's meniscus curves up. Mercury's meniscus curves down.
You measure from the bottom curve of the meniscus.
