convex lens(converging lens)
Because the 2cm lens has 4 times the area of a 1cm lens. (area = Pi*r2)
stroke volume =end diastolic volume - end of systalic volume. But how to measure these volume i don't know?
volume as in TV volume or volume as in books. Answer 2 Volume often just means 'amount' as in 'a large volume of sales'. Also, the volume of a container is a measure of how much 'stuff' it can hold. The volume of a room is length x width x height. The volume of a sphere is 4/3 x pi x radius^3
a greater 1
Not really, for the volume of the bubble is air, not a material of different refractive index. But if you were to fill a transparent balloon with water, say, you would have a lens. Try it with a clear soda bottle.
It is lens. The lens consists of the lens capsule, the lens epithelium, and the lens fibres.
The ocular is the upper lens and objective is the lower lens
)( is a concave lens() is a convex lens
The objective lens
A crystalline lens is the lens in the human eye.
if you are using A+ it is lens
Converging lens is a convex lens.
This depends on the type of lens. If it is a convex lens then they converge at the focus on the other side of the lens. If it is a concave lens, then they diverge and appear to be coming from the focus present on the same side of the lens as the incident ray.
= A lens cap is a cover to a lens on a camera or camcorder.=
The upper lens is called the ocular lens or the eyepiece.
