What is the distance between a lens and its focal point is called?
This is called focal length.
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.
Which term defines the distance from the focal point to either a lens or a mirror?
focal length
What is lens distance?
Lens distance is basically the distance from the lens to the film. This is determined when the lens is focused to infinity and is sometimes called the focal length.
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 is the distance between a lens and its focal point is called?
This is called focal length.
Use the word length in a sentence?
Focal Point:The distance from the Lens to the Focal Point is called the Focal Point.
What is defined as the distance between a lens and its focal point?
focal length of the lens
Where is the focal point in a convex lens?
If you shine a parallel (ie unfocussed) beam of light perpendicular to a convex lens it will focus to a point on the other side. That place is called the focal point of the lens. Its distance to the lens is called the focal length.
What is the focal length of the convex lens?
The distance from the centre of the lens to the focal point.

What is the distance from a lens to one of its foci called?
The distance from the center of a lens to one of its focal points is the focal length of the lens.

focal length

Lens distance is basically the distance from the lens to the film. This is determined when the lens is focused to infinity and is sometimes called the focal length.
What is the focal lentgh of a lens?
It is a plane perpendicular to the lens at the focal distance from the lens. All parallel light entering the lens from a certain direction falls on a single point somewhere on this plane. Where the point of light falls depends on what angle the "wall" of light enters the lens.
Explain how the focal length changes as a convex lens becomes flatter?
The focal length of a lens is the distance from the center of the lens to the point at which it focuses light rays. The bigger the focal length, the more powerful the lens. ChaCha!
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.
