It consists of a tube that surrounds an assembly of two or more mirrors. KaleidoscopeĪ kaleidoscope is an optical tube that contains colored materials and inclined mirrors whose reflections produce a variety of patterns when the tube is rotated. The light rays are reflected from the mirror’s surface to the observer’s eyes. Light rays known as incident rays emanate from the object and strike the mirror. The object and the image are the same size and are equidistant from the mirror. If you place an object in front of a mirror, you will see the image of the object in the mirror. Instead, all the light rays that hit a mirror are reflected.Ī mirror is made by putting a shiny silver nitrate or aluminum backing behind a flat piece of glass. Mirrors do not allow light to pass through. Examples of Reflection in Real Life 1. Images in a Plane Mirror Lines of reflection can be vertical, horizontal, or slopped in any direction. It can be considered as the flip of a shape over the line of reflection.Įvery point on the shape will be at the same distance from the reflection line. Translation and rotation are also isometric or non-rigid transformations.Ī reflection changes the orientation of a shape. This means that the image and pre-image are of the same shape and size. Reflection is a rigid or isometric transformation. The pre-image is the shape before the transformation. The image is the figure after manipulation.
What is reflection?Ī reflection is a transformation that maps all the points of a figure to an image across a fixed line, known as the line of reflection. Today, we will take a look at reflection and explore its examples in real life. In mathematics, there are several types of transformations of shapes and figures.Ī transformation is the manipulation of a shape around a plane or coordinate system.
