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.

What is defined as the distance between a lens and its focal point?
focal length of the lens
The distance from lens to focal point is called?
The distance from a lens to the focal point 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.
How many focal points does a lens have?
A lens has two focal points -- one on each side of the lens. These focal points are where parallel rays of light converge after passing through the lens.
Does a diverging lens have a focal length?
Yes, a diverging lens does have a focal length. The focal length of a diverging lens is negative, as the light rays diverge after passing through the lens.
Length of a lens is the distance from the center of the lens to its principal focus?
That is incorrect. The length of a lens, or focal length, is the distance from the lens to its principal focus.
Why focal length of convex lens is easier to find than a concave lense?
The focal length of a convex lens is easier to find than a concave lens because for a convex lens, the focal length is positive and is measured from the lens to the focal point. In contrast, for a concave lens, the focal length is negative and the rays of light are diverged. This makes it more challenging to find the focal point accurately.
When curvature lens is bigger what happens to the focal point?
When the curvature of a lens is larger, the focal point moves closer to the lens. This means the lens has a shorter focal length and will converge light rays at a point closer to 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!
What kind of lens has a focal point?
A converging lens, such as a convex lens, has a focal point where parallel rays of light converge after passing through the lens. This focal point is where the image of an object placed at infinity will be formed.
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.
What The focal distance of a convex lens is always?
The focal distance of a convex lens is always positive. It is the distance between the lens and the focal point when light rays are parallel and converge after passing through the lens.
