In geometry, a point reflection (also called a point inversion or central inversion) is a transformation of affine space in which every point is reflected across a specific fixed point. When dealing with crystal structures and in the physical sciences the terms inversion symmetry , inversion center or centrosymmetric are more commonly used.
Awal. Refleksi. Refraksi. Rujukan. Optika geometris atau optika sinar menjabarkan perambatan cahaya sebagai vektor yang disebut sinar. Sinar adalah sebuah abstraksi atau "instrumen" yang digunakan untuk menentukan arah perambatan cahaya.
Pantulan atau refleksi adalah perubahan arah rambat cahaya ke arah sisi ( medium) asalnya, setelah menumbuk antarmuka dua medium . Refleksi pada era optik geometris dijabarkan dengan hukum refleksi yaitu: Sinar insiden, sinar pantulan, dan sumbu normal antarmuka ada pada satu bidang yang sama.
The point groups that are generated purely by a finite set of reflection mirror planes passing through the same point are the finite Coxeter groups, represented by Coxeter notation. The point groups in three dimensions are heavily used in chemistry , especially to describe the symmetries of a molecule and of molecular orbitals forming covalent ...

The reflection of Mount Hood in Mirror Lake. Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and water waves.
In geometry, a point reflection or inversion in a point (or inversion through a point, or central inversion) is a type of isometry of Euclidean space. An object that is invariant under a point reflection is said to possess point symmetry ; if it is invariant under point reflection through its center, it is said to possess central symmetry or to ...
