A concave mirror is a curved mirror that bulges inward, like the inside of a bowl. The mirror has a smaller radius of curvature, meaning that the curve of the mirror is more pronounced. As a result, concave mirrors are able to focus light rays that are parallel to the axis of the mirror. This makes them useful for a variety of applications, including telescopes, makeup mirrors, and rearview mirrors in vehicles.

Concave mirrors are able to focus light because of the way that they reflect rays of light. When a ray of light hits a concave mirror, it is reflected in such a way that it appears to come from a single point, known as the focal point. The distance from the mirror to the focal point is called the focal length.

The size and shape of the image produced by a concave mirror depends on the distance of the object from the mirror and the position of the mirror relative to the object. When the object is located at a distance that is equal to the focal length of the mirror, the image is located at the center of curvature of the mirror, which is twice the distance of the focal length from the mirror. When the object is located at a distance that is greater than the focal length, the image is located behind the mirror, and it is inverted. When the object is located at a distance that is less than the focal length, the image is located in front of the mirror, and it is upright.

A convex mirror is a curved mirror that bulges outward, like the outside of a bowl. Convex mirrors are commonly used in places where a wide field of view is needed, such as in parking lots or on the side of vehicles. Unlike concave mirrors, convex mirrors do not focus light, and they produce a smaller, distorted image of the object.

Convex mirrors are useful in certain situations because they provide a wider field of view than flat mirrors. This makes them useful for seeing around corners or for monitoring large areas, such as parking lots or warehouses. However, because the image produced by a convex mirror is distorted, it is not always accurate for judging distance or size.

In conclusion, concave and convex mirrors are both useful for different purposes. Concave mirrors are able to focus light and produce a clear, focused image, while convex mirrors provide a wider field of view but produce a distorted image. Understanding the characteristics and uses of these two types of mirrors can help us make informed decisions about which type of mirror is best suited for a particular application.

A concave mirror has a reflective surface that is curved inward and away from the light source. Unlike convex mirrors, the image formed by a concave mirror shows different image types depending on the distance between the object and the mirror.

You see one of these every time you look into your bathroom mirror, or any time you notice your reflection in a window. Ray Diagrams Incident ray from an infinite point Concave Mirror An incident ray coming from an infinity point that is parallel to the principal axis will be reflected in such a way that it will pass through the Focus F point. In this article, we will discuss more Concave mirrors and Convex mirrors, how they are formed, the uses of convex mirrors and concave mirrors, etc.

Image Formation Using Ray Diagrams Firstly, you will need to understand the image formation using ray diagrams. A mirror is a reflective surface that bounces off light, producing either a real image or a virtual image. As the name suggests, plane mirrors have a plain, polished surface, while spherical mirrors are curved reflecting surfaces. A convex mirror bends light as it reflects the light, and the farther away a point is from the center, the more the light is bent. The image will be real, inverted, and of the same size. An inverted image is an image formed that is upside down whereas an erect image is the same as an object.

Object beyond Centre of Curvature C If the object is placed beyond the Centre of Curvature C , the image will be formed between Focus F and Centre of Curvature C. Spherical Mirror The spherical mirror forms the virtual or real image because spherical mirrors have a consistent curve and constant radius of the curvature. Images Coming soon Image 1: Incident ray from Infinity Incident ray intersecting Focus F Concave Mirror When an incident ray intersects the Focus F of the concave mirror, it will be reflected parallel to the principal axis. When you keep an object in front of a concave mirror, an enlarged image of the object is formed when it is kept close to the mirror and an inverted image of the object is formed when it is kept at a distance. In this article, let us learn about convex mirrors and concave mirrors. What is called a virtual image? It also helps us trace the direction in which the light travels. The size of the image is smaller than compared to that of the object.

Object at Focus F When the object is at Focus F , the image will be obtained at the infinity point. A mirror does not allow the passage of light. The difference between concave and convex mirrors is also among the most commonly asked questions in physics exams and competitive exams. In other words, an image has a right-side-up. One other kind of mirror that you may not have heard of before is a "parabolic reflector.

The size of the image is larger than compared to that of the object. Convex Mirror If the cut part of the hollow sphere is painted from the inside, then its outer surface becomes the reflecting surface. An image that forms behind the mirror is called a virtual image. The size of the image is smaller than compared to that of the object. Introduction You may have observed that whenever you stand in front of the mirror, you get an erect, virtual, and same-sized image of yourself.

As a result, the focal point and center of curvature are located behind the mirror which means they are imaginary and unreachable. These are used whenever you want to take incoming parallel light and focus it together such as on a telescope or a satellite dish. What is meant by erect image? Let us learn about both with the help of diagrams and tables. These mirrors are also used for security in buildings near corners, enabling people to see around a corner before they actually reach it. A concave mirror has a reflective surface that is curved inward and away from the light source. Plane mirrors are built by putting a thin layer of silver nitrate or aluminium behind a flat piece of glass.

To put it simply, mirrors with a reflecting surface that bulges outwards are convex mirrors, whereas concave mirrors have a reflecting surface that bulges inwards. A mirror with a flat surface is called a plane mirror, and a mirror with a curved surface is called a spherical mirror. Watch the video below to understand the concave and convex mirrors A convex mirror is a diverging mirror in which the reflective surface bulges towards the light source. The size of the image is much smaller than compared to that of the object. Spherical mirrors are further divided into Convex and Concave mirrors based on their curves. Images Coming soon Image 4: Incident ray at Pole P Now, you may have completely understood the incident ray at different points of the spherical mirrors concave and convex and their respective reflected rays. Object at infinity When an object is placed at infinity, the convex mirror forms a virtual and erect image at virtual Focus F.

In the convex mirror, the inner side of the spherical mirror will be reflected. How do concave mirrors work? Concave and Convex Mirror: A mirror is a surface that nearly always reflects the light that strikes it. If you imagine the mirror as a part of a larger sphere, then if you view the mirror from a point closer than the center of this sphere, you see an enlarged image. Look further away from the center and you see a diminished image. Also, it can be a real or a virtual image. Now, you might be thinking about how image formation in a convex and spherical mirror happens then. Virtual image forms due to the apparent divergence of light rays from a point.

The two other most common types of mirrors are the ones you ask about: convex and concave mirrors. When the light rays intersect, then it creates a real image. The size of the image is much larger than compared to that of the object. Image Formation by A Concave and Convex Mirror Concave Mirror Object at Infinity When an object is placed at infinity, the image is obtained at the Focus F. However, we will use two rays to understand the ray diagrams in detail.
