Web5 nov. 2024 · When the lens is used this way, the magnifying power can be found with the following equation: (25.2.1) M P 0 = 1 4 ⋅ Φ + 1. where Φ = optical power. When the magnifying glass is held close to the object and the eye is moved away, the magnifying power is approximated by: (25.2.2) M P 0 = 1 4 ⋅ Φ. WebThe magnifying glass is a convex (or converging) lens, focusing the nearly parallel rays of sunlight. Thus the focal length of the lens is the distance from the lens to the spot, and its power is the inverse of this distance (in m). Solution The focal length of the lens is the distance from the center of the lens to the spot, given to be 8.00 cm.
