Number of times image is larger than subject Thus a magnification of 2 indicates the image is twice life-size, while a magnification of 0 5 indicates the image is half life-size
Also called power and indicated by the symbol "x" A 4x riflescope makes the target appear four times closer than when seen with the unaided eye Choose high power for varmint shooting, medium power for big game at moderate ranges, and low power for precise, close range shooting at fast targets
Magnification is the degree to which a lens, mirror, or other device can magnify an object, or the degree to which the object is magnified. The electron microscope uses a beam of electrons to produce images at high magnifications
The effect of an optics, system on the apparent angular size of an object An increase in angular size occurs if the magnification factor is greater than 1 If the factor is less than 1 then demagnification occurs
The magnification of an optical system is simply the number of times an image is enlarged when viewed through the optical system However, magnification can often be a source of confusion, since it is not the magnification that defines the "power" of an astronomical telescope Instead is it the amount of light the telescope can gather, determined by its aperture, that defines the "power" Click here to learn more about magnification
manipulation of the rendered size of a frame Magnification changes both the scale of the frame and the scale of its members and components (see also: scaling)
In a telescope, an increase in the apparent size of an object The process of magnification expands the apparent size of an object by spreading the image, or light, across a large area A large primary mirror or objective lens of a telescope focuses incoming light toward an eyepiece lens that actually magnifies what the telescope sees
The ratio of angular size with and without an optical device With 10X magnification, an object appears ten times as broad Equivalently, it appears to be at one-tenth the distance
The magnification of a lens compared to the naked eye A 10x magnification will make the distant subject appear 10x bigger than it is A common mistake that many binoculars buyers make is to rush out and buy the most powerful they can find While this sounds like a wise move it isn't Powerful pairs are difficult to hold steady and the view is also dimmer It's far more difficult to view a wobbly and dim object at 16x power than having an 8x power with a bright and steady view
changing the size of a font by expanding, or contracting, the positions of the coordinates used to draw the lines which make up the characters Unequal magnification will change the shape of the characters making them wider or narrower than the original
