Magnification is defined as a measure of the ability of a lens or other optical device to magnify a certain image. The ability of a lens to measure size of an object and magnifies to a certain level is the known as a magnification of a lens.
The formula to measure the magnification power of a certain lens is the product of the objective and ocular lens magnification. For example, when using the lower power lens the total magnification is: 10X ocular x10X low power objective = 100X).

Answer:
The correct answer would be
- Concave lens for nearsightedness
- Convex lens for farsightedness
Nearsightedness or myopia is a condition in which a person can see the nearby objects clearly but is unable to see the objects present at a farther distance clearly.
It is usually caused due to elongation of the eyeball or when the lens becomes too curved.
It can be corrected by using a concave or diverging lens of appropriate power.
Farsightedness or hyperopia is a condition in which a person can see the distant objects clearly but is unable to see the nearby objects distance clearly.
It is usually caused due to shortening of the eyeball or when the lens loses its curvature.
It can be corrected by using a convex or converging lens of appropriate power.
Cool front is not a standard weather front. Cold front, warm front and occluded front are all standard weather front. When you say weather front, it is a boundary that separate 2 air masses.
Answer:
