Magnification
Magnification
Magnification (/mæɡnɪfɪˈkeɪʃən/) is the process of enlarging the appearance, not physical size, of something. This term is commonly used in the field of Optics and Microscopy.
Etymology
The term 'Magnification' is derived from the Latin word 'magnificare', which means 'to magnify' or 'to make great'.
Definition
Magnification is defined as the ratio of the size of an image to the size of the object. It is a dimensionless value which indicates how much larger or smaller an image is, compared to the actual size of the object being viewed.
Types of Magnification
There are two types of magnification: linear and angular.
- Linear magnification refers to the ratio of the size of the image to the size of the object in a plane mirror.
- Angular magnification is the ratio of the angle subtended at the eye by the image formed by an optical instrument to the angle subtended at the unaided eye by the actual object.
Related Terms
- Resolution: The ability of an optical instrument to distinguish or separate small or closely adjacent images.
- Field of View: The extent of the observable world that is seen at any given moment.
- Focal Length: The distance between the center of a lens or curved mirror and its focus.
Applications
Magnification is widely used in various fields such as Microscopy, Telescopic observations, Photography, and in Eyeglasses.
