One of the core subjects in physics is the investigation of mirrors. At home, we look in the mirror every morning and evening. We often end up reflecting on our internal states as well as our outward appearance. By themselves, mirrors are a fascinating world. There are mirror museums where you may find all different shaped and sized mirrors that will give you a range of different appearances, including tall, short, obese, and slim. A spherical mirror is a mirror with the shape of a spherical surface carved out of it. Spherical mirrors are classified into two types- concave mirrors and convex mirrors. We have both natural and artificial mirrors in this world.
plane mirrors or concave mirrors.
Convex mirrors are used in sunglasses, magnifying glasses, and rearview mirrors to diverge light beams.
The convex mirror is described by the following terms-
There are certain guidelines that may be used to locate an object's picture, which is as follows-
An upright, virtual picture is always produced by a convex mirror, regardless of the object's location. There are two options for where to place an item to create a picture, which is as follows-
When an item is placed between infinity and the pole of a convex mirror, a decreased, virtual, and erect image forms between the pole and the focus, i.e., behind the mirror. The resulting picture is small, virtual, and upright.
When the object is infinity, a point-sized image is generated behind the convex mirror at the main focus. The resulting picture is greatly reduced, virtual, and erect.
The mirror formula is a mathematical relationship between the mirror's focal length, object distance, and image distance. The formula is as follows-
Where,
u = the separation of the item from the pole.
v = is the separation of the picture from the pole.
f = mirror's focal length
Magnification is the height-to-object ratio of the picture and is expressed in-
If u is the object's distance from the mirror and v is the image's distance, the magnification can be expressed as-
Conventional sign language states that distances measured in the direction of the incident beam are positive, and those measured in the opposite direction are negative. the upward-moving separation.
The following table gives details about the uses of convex mirrors-
Name of the Objects | Description of Uses |
Convex Mirrors in ATMs (Automated Teller Machines) | To enable users to see if somebody is standing behind an automated teller machine, or ATM, convex mirrors are positioned near the machine. This contributes to guaranteeing the security of the users of the ATM. It aids in preventing the problem of stolen money being withdrawn and protects the user's identification when using an ATM. |
Convex Mirror In Automobiles | In order to give drivers a clear view of the road and the cars behind them, convex mirrors are employed as rearview mirrors in automobiles. In cars, convex mirrors help the driver anticipate dangerous circumstances and prevent collisions. |
Convex Mirror in Magnifying Glasses | In reality, magnifying glasses are created by joining two convex mirrors. |
Convex Mirror in Mobile Cameras | Convex mirrors are used by mobile cameras with built-in selfie cameras to take pictures of the user. |
Convex Mirror in Production Process | Convex mirrors play a significant role in the office setting. For various product views, these mirrors are fastened to conveyor belts. This contributes to improving the product's quality by assisting in the prevention of any errors that could arise during production. |
Convex Mirrors in Street Lights | Streetlights employ convex mirrors because they can disperse light beams across a larger region. |
Convex Mirror in Sunglasses | A sunglass lens is developed using convex mirrors. In order to reflect the sun's rays away from the wearer, convex mirrors are used in sunglasses. |
Convex Mirror in Telescope | Convex mirrors are used in telescope construction so that distant objects may be clearly seen as point-sized pictures. |
The following are the primary variations between concave and convex mirrors-

The expanded picture is reflected in a concave mirror. When an item is maintained far enough from a concave mirror, the image can also be inverted. The convex mirror, however, will always provide an almost perfect, much-shrunk picture. Thus, the properties of the created picture may be used to identify the mirror.
Ans. The pole of a spherical mirror is its middle.
Ans. A "diverging mirror" is a term used to describe a convex mirror. When light beams are reflected, they diverge as a result of the mirror’s behavior. This implies that when light is shone on this mirror, the initially parallel light rays that make up the beam might diverge or deviate after striking the convex mirror’s reflecting surface.
Ans. An actual picture of a big thing will appear when an object is placed in front of a concave mirror. On the other hand, a convex mirror always creates a smaller-sized virtual picture.
Ans. The linear distance between the pole and the center of curvature is known as the radius of curvature.
Ans. Because the reflective surface of the convex mirror bulges outward in the direction of the light rays, it is also referred to as a curving, diverging, or fish-eyed mirror. As a result, the mirror serves as the focal point and center of curvature, making them fictitious and out of reach. The resultant picture of the item is essentially upright, imaginary, and reduced in size.
