WebFeb 21, 2024 · The magnification of a lens with focal length 55 mm at a distance of 100 m is m = 0.0005506. To calculate it, follow the steps: Calculate r = sqrt (d²/4 - f × d) = 49.945. Calculate: The distance between the object and lens: g = d/2 + r = 99.945; and The distance between the lens and sensor: h = d/2 - r = 0.05503. WebSimply enter the focal length and the object distance. Then click the Calculate Image Distance button to view the result. Use the widget as a practice tool. Find the Image Distance Enter the focal length of a thin lens and the distance of the object from the lens. Then click on the Calculate Image Distance button to determine the image distance.

A single lens can act like a magnifying glass. Magnification occurs when an object is placed less than one focal length ( f) away from the lens. Maximum magnification occurs when an object is placed exactly one focal length from the lens. If an object is placed farther from the lens than one focal length, the lens will minify instead of ...
