Key Concepts

Magnification

Magnification in mirrors is defined as the ratio of the image height to the object height, and it is also given by the negative ratio of the image distance to the object distance (m = -di/do). For convex mirrors, the magnitude of magnification is less than one, meaning the image is reduced, and the sign indicates whether the image is upright or inverted relative to the object.

Convex Mirrors

A convex mirror is a type of spherical mirror where the reflecting surface bulges outward. Unlike concave mirrors, convex mirrors always form images that are virtual, diminished, and located behind the mirror. They obey the mirror equation with a negative focal length, which results in characteristics such as a reduced size of the reflected image and a wider field of view.

Mirror Equation and Sign Conventions

The mirror equation, 1/do + 1/di = 1/f, relates the object distance (do), image distance (di), and focal length (f) of a spherical mirror. In the context of convex mirrors, the sign conventions dictate that the focal length is negative and the image distance is also negative, signifying a virtual image. Understanding these conventions is essential for accurately determining image properties.

Virtual Images

A virtual image is one that cannot be projected onto a screen because it is formed by the apparent divergence of light rays; the rays do not actually converge at the location of the image. In convex mirrors, the image seen by an observer is virtual, upright, and smaller than the object, providing an important difference from real images formed by concave mirrors.
