1. Convex mirror definition: a convex mirror that uses the outer surface of a spherical surface as a reflective surface.
2. The properties of the convex mirror: the convex mirror diverges the light; the image formed by the convex mirror is reduced; the field of view of the convex mirror with the same diameter is larger than that of the flat mirror.
3. Application of convex mirrors: rear mirrors of motor vehicles, reflectors on street corners, moonlight mirrors on the HSBC building in Hong Kong, etc.
Two . Concave mirror
1. Definition of concave mirror: a concave mirror that uses the inner surface of a spherical surface as a reflective surface.
2. The nature of the concave mirror: the concave mirror can condense the parallel light directed to it at the focal point; if the light source is placed on the focal point of the concave mirror, the light emitted by the light source will become parallel light after passing through the concave mirror.
3. Concave mirror applications: solar cookers, solar cookers, flashlight reflectors, astronomical telescopes, endoscopes for otolaryngologists, searchlights, car headlights, etc.
