What are the 2 types of lenses?

The two most common types of lenses are concave and convex lenses, which are illustrated below in Figure 1. A common bi-convex lens is considered a positive lens because it causes light rays to converge, or concentrate, to form a real image.

What is a lens Class 7?

Lens. A Lens is a type of mirror which refracts the light instead of reflection. Refraction is the bending of a light when it enters a medium.

What is a lens Class 12?

Optics of Class 12. A lens is a transparent polished body bounded on two sides by curved surfaces. In particular, one of the surfaces maybe plane. Spherical lenses have spherical surfaces as bounds. … Diverging lenses convert a parallel beam of rays into a divergent beam.

What is the difference between mirrors and lenses?

Difference Between Lens and Mirror. The lens is a material made of glass or plastic bounded by two surfaces. … A mirror is a reflector that is shiny from one side and reflects the light rays coming from the object to make it appear as an image to the other side. The lens is of two types viz: Concave lens and convex lens.

WHAT IS lens and types?

A lens can focus light to form an image, unlike a prism, which refracts light without focusing. There are two types of lensesconvex and concave. Convex lenses are lenses that curve outwards, they converge parallel light rays to a focal point. Concave lenses are thinner in the middle and thicker at their edges.

What are the four major types of lenses?

The four major types of lenses are the short-focal-length lens, the middle-focallength lens, the long-focal-length lens, and the zoom lens.

What is different types of lenses?

There are two main types of lenses, known as convex (or converging) and concave (or diverging).

What is U and V in ray optics?

The distance of the object from its pole is called the object distance (u). The distance of the image from the pole of the mirror is called the image distance (v). The distance of the principal focus from the pole is called the focal length (f).

WHAT IS lens power?

The power of a lens is defined as the reciprocal of the focal length. … Converging (convex ) lenses have positive focal lengths, so they also have positive power values. Diverging (concave ) lenses have negative focal lengths, so they also have negative power values.

What is a concave lense?

A concave lens is a lens that possesses at least one surface that curves inwards. It is a diverging lens, meaning that it spreads out light rays that have been refracted through it. A concave lens is thinner at its centre than at its edges, and is used to correct short-sightedness (myopia).
