Convex Mirror: A convex mirror, also known as a diverging mirror, is a spherical mirror with a reflective surface that bulges outwards. It is a curved mirror with a reflecting surface that curves away from the incident light, causing the light to diverge or spread out.

Characteristics of a Convex Mirror

Characteristics of a convex mirror are:

• The reflective surface bulges outwards.
• The center of curvature (C) and the focus (F) are both located behind the mirror.
• The image formed is always virtual, upright, and smaller than the object.
• The field of view of a convex mirror is wider than that of a flat mirror.

Uses of a Convex Mirror

• Rearview mirrors: Convex mirrors are commonly used as rearview mirrors in cars, trucks, and other vehicles. The mirror allows the driver to see a wider field of view, making it easier to detect other vehicles or obstacles.
• Security mirrors: Convex mirrors are used in stores, offices, and other facilities to provide a wide field of view for security personnel. The mirror can be placed in strategic locations to help prevent theft and monitor activity.
• Outdoor traffic mirrors: Convex mirrors are used on outdoor roads and highways to help drivers see around corners and blind spots.
• Decorative mirrors: Convex mirrors are sometimes used as decorative mirrors in homes and other settings. They can be used to create interesting visual effects and add a unique touch to the decor.
• Camera lenses: Some camera lenses use convex mirrors to help create a wider field of view.

Image Formation by Convex Mirror

A convex mirror, also known as a diverging mirror, is a type of curved mirror where the reflective surface bulges outwards. The image formation by a convex mirror is different from that of a concave mirror, which is a type of curved mirror that bulges inwards.

When an object is placed in front of a convex mirror, the light rays from the object reflect off the mirror and diverge or spread out. Unlike a concave mirror, the rays never converge to a single point. Instead, they appear to come from a virtual image located behind the mirror.

The virtual image formed by a convex mirror is always upright and smaller than the actual object. The image is also located closer to the mirror than the actual object. This is because the light rays that reflect off the convex mirror diverge outward, making the image appear smaller and located closer to the mirror.

The image formed by a convex mirror is always virtual, meaning it cannot be projected onto a screen. This is because the light rays do not actually converge to form a real image. Instead, they appear to come from a virtual image located behind the mirror.
