Answer:
The power of a convex lens is 5D. At what distance object should be placed from the lens so
that, 2 times larger image is formed.
Solution:
The linear magnification of a thin lens is
where f is the focal length and do is the distance from the lens to the object.
The power of a lens is 1/focal length (measured in meters):
Thus, The linear magnification of a thin lens is
where f is the focal length and do is the distance from the lens to the object.
The power of a lens is 1/focal length (measured in meters):
Answer. 0.1 m.
