What are 3 types of mirrors?

Types of Mirrors

Plane mirror: The images formed from a plane mirror are the reflected images in their normal proportions but reversed from left to right. ...

Convex mirror: These are the spherical mirrors that are curved outward and the image obtained is virtual, diminished and erect for a real object.

Concave mirrors:

A smooth shiny surface of glass which reflects light is called a mirror.

What does a mirror do?

Image result for mirror

A mirror or looking glass is an object that reflects an image. Light that bounces off a mirror will show an image of whatever is in front of it, when focused through the lens of the eye or a camera. Mirrors reverse the direction of the image in an equal yet opposite angle from which the light shines upon it.

How are mirrors made to reflect?

Coating one side of a piece of glass with shiny metals can turn it into a mirror, reflecting light coming toward it. Window glass can reflect only eight percent of light hitting it, while mirrors can reflect 95 percent of light hitting them. The glass in a mirror is usually coated with a layer of silver or aluminum.

What are the 4 rules of mirror?

Image result

This task can be accomplished using just four simple rules:

An incident ray which is parallel to the principal axis is reflected through the focus. ...

An incident ray which passes through the focus. ...

An incident ray which passes through the centre of curvature. ...

An incident ray which strikes the mirror at its vertex.

What is mirror formula?

Image result

The relation between focal length of mirror, distance of the object and distance of the image is known as mirror formula. It is given by. u1+v1=f1.

Why is it called mirror?

The word mirror derives from the French “mirour,” from the Latin “mirari”—to admire. (The Romans themselves, however, used the word “speculum,” from “specere”—to look, or behold.) METAL MIRRORS — Mirrors were used by the ancient Egyptians as early as c. 2900BC.

What are types of mirror?

Spherical mirrors can be of two types- Concave mirror and convex mirror. Concave mirror - A spherical mirror whose outer surface is silvered and inner surface is used for reflection is called concave mirror. In concave mirror, the reflecting surface is located towards the center of the sphere.

Silver. The reflective layer on a second surface mirror such as a household mirror is often actual silver. A modern "wet" process for silver coating treats the glass with tin(II) chloride to improve the bonding between silver and glass.
