Final answer:
The range of magnification possible with a 7.0 cm-focal length converging lens is from 1 to infinity.
Step-by-step explanation:
The range of magnification possible with a 7.0 cm-focal length converging lens can be calculated using the lens formula. The lens formula is given by:
1/f = 1/v - 1/u
Where f is the focal length of the lens, v is the image distance, and u is the object distance. By rearranging the formula, we can calculate the magnification (M) as:
M = - v/u
So, to find the range of magnification, we need to determine the maximum and minimum values of v and u. With a converging lens, the maximum magnification occurs when the object is placed at the focal length of the lens (u = f) and the image is formed at infinity (v = ∞). This results in an infinitely large magnification. The minimum magnification occurs when the object is at infinity (u = ∞) and the image is formed at the focal length of the lens (v = f). This results in a magnification of 1. Therefore, the range of magnification possible with a 7.0 cm-focal length converging lens is from 1 to infinity.
