Optical magnification is the ratio between the apparent size of an object (or its size in an image) and its true size, and thus it is a dimensionless number. Optical magnification is sometimes …

Sep 22, 2025 · Enter the distance of the object from the lens and the distance the image is formed from the lens to determine the Magnification. This calculator can also determine the image …

Apr 16, 2025 · An object's magnification is generally given by the equation M = (hi/ho) = - (di/do), where M = magnification, h i = image height, h o = object height, and d i and d o = image and …

Sep 23, 2024 · Learn all about the magnification formula in biology for your IGCSE exam. This revision note includes diagrams, worked examples and examiner tips.

Dec 1, 2025 · An image that is double the size of the object would have magnification m = 2. For both convex and concave lenses, these equations can be used to calculate image size and …

The magnification formula is a mathematical expression that quantifies how much larger or smaller an image appears compared to the actual object.

Jul 23, 2025 · A lens's magnification is the relationship between the size of the image produced and the size of the target. Lenses may also be used in groups to reduce blurriness or distortion …

is a measure of the size of an image compared to the size of the object. Lenses and curved mirrors can produce magnified images. The magnification produced by a lens can be …

What is the formula for magnification? The formula for magnification is M=Hi/Ho=-Di/Do.

Let's explore the magnification formula (M= v/u) for lenses and see how to find the image height and its nature (whether it's real or virtual).
