The convex mirror always makes a virtual image of the object, and the convex mirror’s image is always smaller than the actual object’s size. As a result, convex mirrors are most commonly used in situations where larger objects must be examined in a smaller space. Convex mirrors are used as inside mirrors in vehicles because they have a greater visual field than concave and flat mirrors.
Convex Mirror
If the hollow sphere’s cut half is painted from the inside, the sphere’s outside surface becomes the reflecting surface. A convex mirror is the name given to this type of mirror. A convex mirror is a spherical mirror with its reflecting surface bent outwards.
The back of the mirror is painted, allowing reflection solely from the bulged outward portion. The bulged outwards surface of the spoon can be thought to be a convex mirror.
It’s also known as a diverging mirror because the light that reflects off its surface diverges in numerous ways but appears to come together at some locations to form a virtual, erect picture of reduced size.
Some examples of concave mirror in daily life are:
- Sunglasses
- Vehicle mirrors
- Magnifying glasses
- Street light reflectors
Properties of Convex Mirror
- A diverging mirror is also known as a convex mirror because it diverges light as it hits its reflecting surface.
- Convex mirrors always produce or witness virtual, erect, and decreased images, regardless of the distance between the object and the mirror.
Function of Convex Mirror
A convex mirror, also known as a curved mirror, has a reflective surface that bulges toward the light source. A curved mirror’s surface can be convex, meaning it bulges outward, or concave, meaning it bulges inward. Because a convex mirror reflects light outwards, it cannot be used to focus light.
Because the focus and centre of curvature are fictitious positions inside the mirror and cannot be reached, convex or curved mirrors always produce a virtual picture. This means that convex mirror pictures cannot be projected onto a screen. Also, the picture is smaller than the projected item, but as the object approaches the convex mirror, it grows larger.
Uses of Convex Mirror
The uses of convex mirror are mentioned below:
In ATMs: On top of ATM machines, convex mirrors are commonly used. The mirror’s placement allows the withdrawer to see if the person behind them is looking at his ATM pin or other essential facts. With the use of a convex mirror, the withdrawer may also see who is standing behind them.
As Rear-View Mirrors: Convex mirrors are used as rear-view mirrors in automobiles, buses, motorbikes, and other vehicles. The diver can use these rear-view mirrors to watch for vehicles and traffic behind them. It also allows the driver to perceive enormous objects in miniature, such as trucks and buses.
In Parking Lots: In parking lots, convex mirrors are also employed. The concave mirrors in the parking lot assist users in parking their automobiles in the correct location by allowing them to check the vehicles behind them.
For Security Purposes: For security reasons, convex mirrors are commonly utilised in hallways and stores. In a narrower view, it is easier to perceive the larger items behind us.
Inside Buildings & Offices: Inside buildings, hospitals, and offices, convex mirrors are installed. These convex mirrors allow individuals to see around corners while avoiding colliding with one another.
Characteristics of Convex Mirrors
The following are the properties of convex mirrors:
- Only erect and imaginary images are produced by convex mirrors.
- The virtual, upright, and smaller object reflected by the mirror will be virtual.
- The virtual image is always displayed regardless of the object’s distance from the mirror.
- Convex mirrors’ outer surfaces are the only ones that reflect.
Conclusion
A convex mirror is a spherical reflecting surface with a bulging side that faces the source of light. Convex mirrors, often known as fish-eye mirrors by car enthusiasts and diverging mirrors by physicists, have a wide range of applications. The phrase ‘diverging mirror’ comes from the fact that when rays are reflected, they diverge. When a parallel light beam strikes a convex mirror, it reflects outwards and travels away from an imaginary focus point directly.
