what are reflections in math?
482585
In geometry, a reflection is a type of rigid transformation in which the preimage is flipped across a line of reflection to create the image. Each point of the image is the same distance from the line as the preimage is, just on the opposite side of the line.

the line y = -x is the point (-y, -x). Remember that each point of a reflected image is the same distance from the line of reflection as the corresponding point of the original figure. The line of reflection will lie directly in the middle between the original figure and its image.

Reflection is the phenomenon which sends back the light in the same medium. The medium doesn't change. Refraction is the phenomenon which sends back the light in the different medium.

An infinity mirror (also sometimes called an infinite mirror) is a configuration of two or more parallel or nearly parallel mirrors, creating a series of smaller and smaller reflections that appear to recede to infinity.

Reflection generally occurs in shinny surfaces that allow rebounding of light without permitting penetration through it. While refraction occurs in transparent surfaces that allows bending of the ray to a different medium. In the case of reflection, the medium in which light propagates remains the same.

What is the difference between light and reflection ? Reflection is when light bounces off an object, while refraction is when light bends while passing through an object. When you look at a mirror the light bounces of the mirror from different angles, so you can see your reflection.

As nouns the difference between shadow and reflection is that shadow is a dark image projected onto a surface where light (or other radiation) is blocked by the shade of an object while reflection is the act of reflecting or the state of being reflected.

As nouns the difference between reflection and echo is that reflection is the act of reflecting or the state of being reflected while echo is echo (a reflected sound that is heard again by its initial observer).

(Major: Physics, Minor:..." Reflection and refraction are wave phenomena; they happen when a wave meets a boundary between two different substances (or media). Reflection is when a wave bounces off of the boundary. Refraction is when a wave passes through, but changes direction.

A convex mirror is a spherical mirror where the mirrored surface is on the outside of the spherical curve. And a concave mirror is a spherical mirror where the mirrored surface is on the inside of the spherical curve. Plane mirrors produce virtual, upright images that are the same size as the object.

Reflection of light. Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. ... For a rough surface, reflected light rays scatter in all directions.

There are two types of reflection: specular and diffuse. Specular reflection * occurs on smooth surfaces. Diffuse reflection * occurs on rough surfaces. The rougher the surface, the more diffuse the reflection.

Reflection is when light bounces off an object, while refraction is when light bends while passing through an object. When you look at a mirror the light bounces of the mirror from different angles, so you can see your reflection.

Primary reflection examines its object by abstraction, by analytically breaking it down into its constituent parts. It is concerned with definitions, essences and technical solutions to problems. In contrast, secondary reflection is synthetic; it unifies rather than divides.

Regular reflection occurs when light reflects off a very smooth surface and forms a clear image. Diffuse reflection occurs when light reflects off a rough surface and forms a blurry image or no image at all.

The reflection of light can be roughly categorized into two types of reflection. Specular reflection is defined as light reflected from a smooth surface at a definite angle, whereas diffuse reflection is produced by rough surfaces that tend to reflect light in all directions (as illustrated in Figure 3).

Reflection is flipping an object across a line without changing its size or shape. Rotation is rotating an object about a fixed point without changing its size or shape.
