A spherical mirror whose reflecting surface is curved inwards is called a concave mirror.A spherical mirror whose reflecting surface is curved outwards is called a convex mirror.a parallel beam of light falling on this converges at a point after reflection in a concave mirror.a parallel beam of light falling on this mirror diverges at a point after reflection in a convex mirror.concave mirror is also know as converging mirror.convex mirror is also known as diverging mirror.

Convex Mirror:
A convex mirror is a curved mirror that bulges outward. It is also known as a diverging mirror because it diverges the light rays that strike it. The center of curvature is behind the mirror and the radius of curvature is a negative value. Convex mirrors have a reflective surface on the outside of the curve and a hollow interior.

Properties and Characteristics of Convex Mirror:
1. Reflective Surface: The reflective surface of a convex mirror curves outward, away from the viewer.
2. Image Formation: Convex mirrors always form virtual, erect, and diminished images regardless of the position of the object.
3. Field of View: Convex mirrors provide a wider field of view as they reflect light rays over a larger area.
4. Focal Point: The focal point of a convex mirror is located behind the mirror.
5. Converging Effect: Convex mirrors diverge the light rays that fall on them, causing them to spread out instead of focusing at a point.

Uses of Convex Mirrors:
1. Rearview Mirrors: Convex mirrors are commonly used as rearview mirrors in vehicles. They provide a wider field of view, allowing the driver to see a larger area behind the vehicle.
2. Security Mirrors: Convex mirrors are used in areas where surveillance is required, such as stores, parking lots, and warehouses. They provide a wide-angle view, allowing for better monitoring of the surroundings.
3. Decorative Purposes: Convex mirrors are also used for decorative purposes. They can enhance the aesthetics of a space by reflecting light and creating an illusion of depth.

Concave Mirror:
A concave mirror is a curved mirror that bulges inward. It is also known as a converging mirror because it converges the light rays that strike it. The center of curvature is in front of the mirror and the radius of curvature is a positive value. Concave mirrors have a reflective surface on the inside of the curve.

Properties and Characteristics of Concave Mirror:
1. Reflective Surface: The reflective surface of a concave mirror curves inward, towards the viewer.
2. Image Formation: Concave mirrors can form both real and virtual images, depending on the position of the object relative to the focal point.
3. Field of View: Concave mirrors provide a narrower field of view compared to convex mirrors.
4. Focal Point: The focal point of a concave mirror is located in front of the mirror.
5. Converging Effect: Concave mirrors converge the light rays that fall on them, causing them to focus at a point.

Uses of Concave Mirrors:
1. Reflective Telescopes: Concave mirrors are commonly used in reflective telescopes to gather and focus light. They are used in the primary mirror of the telescope, allowing for a wider aperture and better image resolution.
2. Makeup and Shaving Mirrors: Concave mirrors are used in makeup and shaving mirrors to magnify the reflection, allowing for a closer and more detailed view of the face.
3. Headlights and Flashlights: Concave mirrors are used in headlights and flashlights to focus the light beam and increase its intensity.

In conclusion, convex and concave mirrors have distinct properties and characteristics. Convex mirrors diverge light and provide a wider field of view, while concave mirrors converge
