reflection
- noun
- /rɪˈflɛkʃən/
- Specialized
- In geometry class, we learned that a reflection flips a shape across a line to create its mirror image.
That's called particle antiparticle symmetry or reflection charge, reflection symmetry.
- That's called particle antiparticle symmetry or reflection charge, reflection symmetry.
Examples
-
And this was the operation of reflection, a mirror point M.
-
Let me just label them X axis, reflection Y axis.
-
So that was a reflection about the Y axis.
-
Graham states that "surely the second should be a simple reflection of the first."

It's not hard to do if you take advantage of symmetries like rotations and reflections.

In the illustrations at right, the zeroth order (000) reflection corresponds to a constant added to the density, and the phases for the (200) and (300) reflections have been set equal to 0.

Dixon (1995) observed eighth-grade students in a bilingual classroom exploring the geometric concepts of reflection and rotation and also concluded that using computer-based dynamic instruction had a positive effect.

A reflection across the X-axis changes the orientation of the figure while keeping its shape identical.
-
After applying the reflection transformation, the triangle appeared to be mirrored perfectly on the graph.

Etymology
Reflection comes from Latin parts re- 'back' and flect 'bend', and in math it means flipping a shape across a line so it becomes a mirror image. That's why a mathematical reflection changes orientation like looking in a mirror.
