What is Convex Mirror?

A convex mirror, also known as a curved mirror, has a reflective surface that bulges towards the light source. Because a convex mirror reflects light outwards, it cannot be utilized to focus light. A convex mirror is also known as a diverging mirror because when light strikes its reflecting surface, it diverges. Convex mirrors always produce virtual, erect, and reduced pictures, regardless of the distance between the item and the mirror.

## Image Formation by Convex mirror

When it comes to the position of an object in a convex mirror, there are two options.

1. When Object is between infinity and pole

• A decreased, virtual, and an erect picture is generated between the pole and the focus, i.e. behind the mirror, when the object is between infinity and the pole of a convex mirror.
• The image that is created is small, virtual, and upright.

2. When Object is at infinity

• A point-sized picture is created at the principal focus, which is behind the convex mirror, while the object is at infinity.
• The image that is created is greatly distorted, virtual, and upright.

## Uses of Convex Mirror

• Convex mirrors are used in vehicles as rearview mirrors to see traffic behind them.
• Shop security mirrors are made of large convex mirrors.
• They’re utilized in driveways, roads, and alleyways to keep all bikers and motorists safe around curves and turns, as well as in other situations where sight is limited.

## Conclusion

• A spherical mirror’s pole is the center of the reflecting surface.

• The center of curvature of a spherical mirror is the center of the sphere created by the reflecting part of the mirror. C is the most common abbreviation for it.

• The principal axis is a straight line that passes through the pole and the spherical mirror’s center of curvature.

• After reflection, incident rays that are parallel to the principal axis appear to diverge from a common point on the primary axis, which is known as the principal focus of a convex mirror. It’s commonly symbolized with the letter F.

• The focal length is the distance between the pole and the mirror’s main focus.

• Convex mirrors include magnifying glasses and telescopes.
