Q: Remarks: The ability of a lens to magnify objects led to the inventions of readi

Solution: Useful fact: When the object is at a far off distance ( infinity ), then the light rays incident on the lens are parallel. In this case, they refract and converge on the other side at a distance equal to the focal length to form the real image. Ans: The distance from the lens to its focal point

Remarks: The ability of a lens to magnify objects led to the inventions of reading glasses, microscopes, and telescopes.

Question: If the lens is used to form an image of the sun on a screen, the lens should be located at a distance from the screen equal to:

* the radius of the surface of the lens.

* a value between the distance to the focal point and twice the distance to the focal point.

* the sum of the radii of the two lens surfaces.

* twice the distance from the lens to its focal point.

* the distance from the lens to its focal point.
