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.
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 the distance between a lens and its focal point is called?
This is called focal length.
Which term defines the distance from the focal point to either a lens or a mirror?
focal length
What is defined as the distance between a lens and its focal point?
focal length of the lens

What is the focal length of the convex lens?
The distance from the centre of the lens to the focal point.
What kind of lens has a focal point?
Convex lenses have a focal point.
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 are two ways to focus a hand lens?
by either moving the object understudy to the focal point of the lens or to move the lens until the object is at the focal point.
Use the word length in a sentence?
Focal Point:The distance from the Lens to the Focal Point is called the Focal Point.
The distance from lens to focal point is called?
It is called the focal length.
What is the distance between a lens and its focal point is called?
This is called focal length.
Why is convex lens used for myopia?
Convex lenses cause the focal point to appear behind the lens (positive convergence). In myopia, the focal point lies somewhere between the lens and the retina, it needs to converge at a point farther than it is converging, this is why a convex lens is used, to push the focal point back so it will hit the retina. A concave lens would do the opposite for hyperopia (the focal point appears behind the retina), it will adjust the focal point to lie more anteriorly and land on the retina.
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!
Lens that converges light from a distant object at its focal point?
A convex lens.
