Spherical mirrors have an uniform curve and constant radius of curvature, they provide a virtual or actual picture. It is divided into two varieties based on the surface painting of the spherical mirror: Concave Mirror: Concave mirrors are created when the outer surface of a spherical mirror is painted. Convex Mirror: Convex mirrors are created […]

The lens is a transparent medium that is bordered by two surfaces, at least one of which must be curved in order for the lens to function. When the distance between the two sides of a lens is exceedingly short, it is said to be thin. When a lens has a positive focal length, it

The focal length of an optical system is the inverse of the system’s optical power; it measures how strongly the system converges or diverges light. A system with a positive focal length converges light, while one with a negative focal length diverges light. A system with a shorter focal length bends the rays more sharply,

There are two types of spherical mirrors—concave and convex. Concave mirrors have an inwardly curved reflecting surface. Concave mirrors are also known as converging mirrors because they collect or converge the rays of light parallel to the principal axis that falls on them to a single focal point. Concave mirrors concentrate light rays and can

The term power of a lens signifies its capacity to bend the light (converge or diverge) that falls on it. A lens of a shorter focal length tends to bend light rays more and has more power. The lens with a longer focal length will have the opposite nature of less bending of light and

A convex mirror, or simply a curved mirror, is a mirror in which a bright spot explodes toward a light source. The surface of the curved mirror can be convex, which means to protrude outward, or curve, to protrude inside. A convex mirror reflects light outside so it is not used to focus on light.

Convex mirror, also called a diverging mirror, is a mirror with a reflective surface that bulges towards the light source. It reflects light outwards. It cannot be used to focus light. Although the projected image appears smaller than what is actually being projected, the image grows larger as the object gets closer to the convex

Definition – Convex Lens A convex lens is designed so that a ray of light passes through the lens, and the focus is brought to a particular point. It Is also known as an optical device used to convert the transmitted light to form an image. It is made upon a spherical surface like a

What stream to choose after 10th? Introduction A mirror is a polished surface that reflects light to form images. There are mainly two types of mirrors – plane and spherical. A concave mirror and a convex mirror are spherical mirrors. Spherical mirrors form a part of a hypothetical sphere. They are distinguished based on their

In a combination of thin lenses, we use two thin lenses, a convex lens and a concave lens. Lenses formed after combinations of two or more lenses are termed compound lenses. When two lenses, such as a convex and a concave lens combine, the first lens forms an image that serves as an object for
