The origin of a coordinate system is placed at the center of curvature of a spherical mirror with radius of curvature $R=59.3 \mathrm{~cm}$ (see the figure). An object is placed at $x_{\mathrm{o}}=39.5 \mathrm{~cm} .$ What is the mirror's magnification?

Key Concepts

Spherical Mirror

A spherical mirror is a type of reflective surface that is a portion of a sphere. Its geometry means that its reflective properties, including the convergence or divergence of reflected rays, are determined by its radius of curvature.

Focal Length

The focal length is a measure of how strongly a mirror converges or diverges light. In a spherical mirror, the focal length is defined as half the radius of curvature, serving as the key parameter in determining image position and properties.

Mirror Equation

The mirror equation is a fundamental relation in geometrical optics that links the object distance, image distance, and focal length through the formula 1/f = 1/do + 1/di. It provides a method to calculate one quantity when the other two are known, governing the image formation process.

Magnification

Magnification in mirror systems is defined as the ratio of the image distance to the object distance, often including a sign convention to indicate image orientation. It quantifies how much larger or smaller the image is compared to the object and indicates whether the image is inverted relative to the object.
