Magnification ofa convex mirror is always positive, but that of a concave mirror may be both positive or negative . This magnification can tell us about the nature of the image based on the sign itself. If the ratio is negative then the image is real and inverted. Can microscope magnificatio...
The present invention relates to a concave magnification mirror that can magnify the image of an object reflected in the mirror, can maintain the definition of the image at a constant level at all times irrespective of the separation distance between the mirror and the object, and can be ...
sometimes erect and in other cases are inverted. The size of the image and whether it is erect or inverted, real or virtual, depend on the distance of the object from the lens or mirror relative to the focal length and on the type of lens or mirror (plane, convex, or concave) ...

Optical Mirror: A mirror is an optical element that uses reflection. Mirrors can be divided into flat mirrors, spherical mirrors and aspheric mirrors according to their shapes. Products are widely used in optical equipment, teaching, industrial lenses, camera, ...

Mirror and Magnification Equations In addition to ray diagrams, we can use equations to predict the characteristics of an image on a concave mirror. There are two equations that you can use: Mirror Equation: allows you to calculate the location of the image The image distance, d i , is ...
