What kind of lens has a focal point?
Convex lenses have a focal point.
What creates an image that is reflected through a focal point?
a convex lens
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.
Why is the focal point of a convex lens real and that of a concave lens virtual?
because in a convex lens rays join at a common point after refrection but in case of a concave lens they appears to come from a common point.
What is a convex lens that focuses light to form an image at the focal point?
A magnifying lens. In a Refracting Telescope, a convex lens focuses light to form an image at the focal point.
What kind of lens has a focal point?
Convex lenses have a focal point.
What is the focal length of the convex lens?
The distance from the centre of the lens to the focal point.
What creates an image that is reflected through a focal point?
a convex 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.
Lens that converges light from a distant object at its focal point?
A convex lens.

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.
Which lens and which mirror forms a visible focal point?
A concave lens and a convex lens are what you're looking for. / | ∙ \

Why is convex lens called converging lens?
All of the light entering the lens converges on the other side to a single point, the lens' focal point.
