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.
| Object’s Position | Image’s Position | Image’s size | Image’s Nature |
| Between infinity and the mirror’s pole | Behind the mirror and between pole and infinity | Diminished | Virtual and Upright |
| Object at infinity | Behind the mirror, at focus F | lot smaller and point-sized | 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.
Summary
- 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.
