The radius of curvature of a convex mirror is 1.00 ×10^2...

The radius of curvature of a convex mirror is $1.00 \times 10^{2} \mathrm{~cm}$. An object that is $10.0 \mathrm{~cm}$ high is placed $25.0 \mathrm{~cm}$ in front of this mirror. Using a ray diagram drawn to scale, measure (a) the location and (b) the height of the image. The mirror must be drawn to scale.

Key Concepts

Convex Mirrors

Convex mirrors are curved outward and always produce virtual, upright, and reduced images. They are commonly used in applications such as vehicle side mirrors because they provide a wider field of view.

Focal Length

In mirror problems, the focal length is related to the radius of curvature by the relation f = R/2. For convex mirrors, the focal length is taken as positive or negative based on the adopted sign convention, typically negative for convex mirrors, indicating that the focus is virtual.

Mirror Equation and Sign Conventions

The mirror equation 1/f = 1/do + 1/di is essential for relating the object distance, image distance, and focal length. Correct application of sign conventions is crucial, especially for convex mirrors where the image distance is negative to signify the virtual nature of the image.

Ray Diagrams

Ray diagrams are used to graphically determine the location, orientation, and size of the image by tracing representative light rays. For convex mirrors, rays such as the one parallel to the principal axis (which appears to come from the focal point) are key to constructing these diagrams.

Magnification

Magnification in mirror systems is defined as the ratio of the image height to the object height and is mathematically represented as m = -di/do. It provides information on the relative size and orientation of the image compared to the object.
