# How are light rays reflected in the mirror?

Light rays move in a straight path towards the mirror and are reflected inwards to meet at a location known as the focal point. Concave mirrors are great for make-up mirrors since they distort the image. Convex mirrors don't reflect as much so less distortion is created.

Mirrors can be divided into two main types: flat and curved. A flat mirror is simply one side of a plane, while a curved mirror is made up of several small planes joined together to form a single surface. Flat mirrors are usually made of glass or plastic, while curved mirrors can be made of metal or hard rubber compounds.

The simplest type of mirror is the flat one. They are easy to make and often used for decorative purposes. The best way to understand how a flat mirror works is to look at it from the side. You will see that there is no depth to it; instead, it appears flat. This is because all objects outside of the mirror (including you) create a picture on its surface that is then mirrored back at you.

You can also view a flat mirror as an extension of any object behind it. For example, if there is a table behind you when you look in a mirror, then you are seeing part of that table through the flat mirror.

## Which mirror should be used to focus a light beam?

Concave mirrors are inwardly curved mirrors. They are used to concentrate light by reflecting it inward into a single focal point. Depending on the distance between the mirror and the reflected item, concave mirrors produce several forms of pictures. Very close to the mirror the image is small and bright; as you get further away from the mirror the image gets bigger but farther away.

Fresnel lenses are composed of many tiny, evenly spaced convexities on their surface. The lens focuses images by bending light waves toward its center. It can create very thin, brightly lit images from a great distance.

Glasses with flat surfaces and straight edges are called plane mirrors. They reflect only part of the incident light wave in a perpendicular direction. The other parts of the wave propagate through the glass unaltered. Plane mirrors are useful because they allow us to look at objects that are hidden from view by overhanging structures or surrounding people. For example, when you walk into a room where there is a window behind which someone is standing, the person cannot see you unless you move first into view then out of sight again. As you pass by the window, your image appears in front of it as if by magic!

For projection televisions and large-scale photographs, a spherical mirror is needed to reflect an even distribution of light from a source such as the sun.

## How do concave mirrors reflect light?

Mirrors that are concave When parallel light beams strike a concave mirror, they reflect inwards to a focal point (F). The focal length of the mirror is the distance from the surface to the focus; for a concave mirror it is equal to the radius of curvature of the mirror.

How does a convex mirror work? Convex mirrors don't focus light into a single point like concave mirrors do, but rather spread out the light over a wide area. If you were to look into a large convex mirror, you would see many small images of yourself surrounded by a halo of bright light. This is because every point on an object's surface reflects some portion of the incident light back toward where it came from. Thus, far away objects appear dimmer than close-up objects, which appear brighter than objects in between. Objects that are completely flat reflect no light-they appear black to the eye-while objects with peaks or valleys will reflect light in different directions, creating patterns of dark and bright areas on the finished image.

Concave mirrors have been used since ancient times for various purposes including weapon sights, glass painting, and scientific instruments. Modern uses include camera lens reflections, bar codes, and other optical devices.
