D) Convex lens with focal length 25 cm
Answers
Answer:
A) Convex lens with focal length 10cm
Answer:
The correct option to this question is A) Convex lens with a focal length of 10 cm.
Explanation:
The lens's magnifying power increases with decreasing focal length. Magnifying power is a lens's capacity to enlarge an image by how much. The least distance of distinct vision, or LDDV, and the focal length of the lens are directly correlated. Your eyes can easily focus on an object up to its LDDV. The geometry of the optical system connects the magnifying power, or how much the thing being observed seems expanded, and the field of view, or the size of the object that can be seen.
Thus, the ratio of the angle the image at the eye occupies to the angle the object occupies is known as the magnifying power of the lenses.
