Which statement is true about a farsighted (hyperopic) eye?
a. the image point is in front of the retina; a converging eyeglass lens is used to correct this condition.
b. the image point is in front of the retina; a diverging eyeglass lens is used to correct this condition.
c. the image point is behind the retina; a converging eyeglass lens is used to correct this condition.
d. the image point is behind the retina; a diverging eyeglass lens is used to correct this condition.

The correct answer is C. I leave an attached image to have a clearer idea of the light process that uses the Light when entering the eye. When you have farsightedness, the image is formed behind the eye so the defective effect is generated.

What is sought with the lenses is to correct this condition and put the image back at the point of the retina.

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
