Spherical mirrors, integral to optics, come in concave and convex forms, each with distinct functions. Concave mirrors focus light to create real or virtual images, useful in telescopes and magnifying tools. Convex mirrors diverge light, providing a wider field of view for safety in vehicles and public spaces. Understanding their properties is crucial for designing optical systems and predicting image formation.

Concave mirrors have a reflective surface that curves inward and can focus parallel rays of light to a point
Convex mirrors have a reflective surface that bulges outward and cause parallel rays to spread apart, providing an expanded field of view
The spherical mirror equation relates the focal length, object distance, and image distance and is essential for predicting image formation
Concave mirrors are used in applications that require magnified views, such as in shaving or makeup mirrors, and in scientific apparatus like reflecting telescopes
Convex mirrors are ideal for situations where a larger field of vision is beneficial, such as in vehicle side mirrors and security cameras
Distances measured in the direction of incoming light are positive, while those measured in the direction of reflected light are negative in the spherical mirror equation
Ray diagrams include the principal axis, focal point, and characteristic rays to illustrate the formation of images
Ray diagrams are indispensable for understanding the principles of reflection and the behavior of light in optical systems
Spherical mirrors are utilized in a multitude of practical applications, such as in searchlights, solar furnaces, and safety and surveillance systems
