When the magnification of a mirror is negative? Magnification is negative in a concave mirror. The magnification of a concave mirror is given by the ratio of the height of the image to the height of the object. Hence,if the image is inverted and real the magnification willbe negative. What...
Magnification Equation:The magnification of a mirror is given by {eq}M = \dfrac{h_i}{h_o} = -\dfrac{d_i}{d_o} {/eq}, where {eq}h_i {/eq} and {eq}h_o {/eq} are the heights of the image and object, respectively, and {eq}d_i {/eq} and {eq}d_o {/eq} are the...

mirror is virtual. It appears to be behind the mirror, at a distance equal to that of the object in front, although the rays of light from the object do not penetrate the mirror but are reflected from it. Images of the same size as the object are sometimes produced, as in the case ...
What is the focal length of a plane mirror? What is a total scan transducer? What is hyperopic presbyopia? What is a shorty Barlow lens? What is astigmatism in the eye? What is a hypermature cataract? What is a 2x Barlow lens?
Conic mirror reflectometers are used to measure the diffuse reflectance and total integrated scatter of surfaces. In spite of the long history of using conic mirrors for these purposes, the maximum magnification of the three primary types of conic mirror (hemisphere, hemiellipsoid, and dual parabolo...
