What is the focal point in a composition in art called?
In art a composition's focal point is actually called the focal point. There may be multiple focal points, in which case the main one is the focal point and the others are secondary focal points. You can recognize the focal point because it is somehow set apart from the rest of the composition.
Difference between focal point and focal length?
The focal point is the point where light converges after it passes through a concave lens. The focal length is the distance of the focal point to the lens. Same for a convex lens, except that the focal point is the imaginary point from where light deflected from lens seems to have emerged.
Length of a lens is the distance from the center of the lens to its principal focus?
It is called the focal length. It is equal to 1/2 times r, and is positive on concave mirrors and negative on convex mirrors.
What kind of lens has a focal point?
Convex lenses have a focal point.
The distance from lens to focal point is called?
It is called the focal length.
What is focal intra-alveolar?
Intra-alveolar means between the alveoli. Focal means within a limited area. There are both adjectives and the phrase is missing a noun. (In other words, focal intra-alveolar...what?)

What is the english translation of the irish sentence cén focal atá i gceist?
"cén focal atá i gceist" means "which word is in question"
Why does the focal length of a mirror not depend on the mirror material when the focal length of a lens does depend on the lens material?
The focal length for a mirror is determined by the law of reflection from the mirror surface. This law is not governed by the material that the mirror is made by. This means that the focal length depends only on the radius and curvature. Conversely, the focal length of a lens depends on the indices of refraction of the lens meterial and the surrounding medium.
What does no focal bony signal abnormalities are demonstrated mean?
what does generalised osteopenia of the bones means
What does this mean there is no evidence of a focal nodule currently?
This means that there is no visible abnormal growth or mass in a specific area of the body, usually referring to a nodule on an imaging test like an ultrasound or CT scan. It indicates that there is no focal point of concern at the present time.
What is the prefix for focal?
the prefix for focal is infocals
What is defined as the distance between a lens and its focal point?
focal length of the lens

Where is the focal point of a lens?
The focal point of a convex lens is the point where light rays parallel to the axis are brought to a point. What this means in practical terms is that, in a camera, the lens focuses to its focal point, which is set at the film plane. This creates the image. Today, with auto-focus lenses for most consumer cameras, we don't think about the focal point much. When the auto-focus fails, however, which it can do from time to time, the photographer must manually bring the image to the focal point.
How does the focal plane change as you change magnification?
It does not. For an explanation of "focal plane" see the question What is the focal plane?
