  2. Mirror image - Wikipedia

    en.wikipedia.org/wiki/Mirror_image

    In geometry, the mirror image of an object or two-dimensional figure is the virtual image formed by reflection in a plane mirror; it is of the same size as the original object, yet different, unless the object or figure has reflection symmetry (also known as a P-symmetry).

  3. Magnetic mirror - Wikipedia

    en.wikipedia.org/wiki/Magnetic_mirror

    Magnetic mirrors also occur in nature. Electrons and ions in the magnetosphere, for example, will bounce back and forth between the stronger fields at the poles, leading to the Van Allen radiation belts. [citation needed] Centrifugal magnetic mirrors use supersonic rotation to stabilize the mirrors, which helps heat plasma to fusion temperatures.

  4. Perfect mirror - Wikipedia

    en.wikipedia.org/wiki/Perfect_mirror

    A very complex dielectric mirror can reflect up to 99.999% of the light incident upon it, for a narrow range of wavelengths and angles. A simpler mirror may reflect 99.9% of the light, but may cover a broader range of wavelengths. Almost any dielectric material can act as a perfect mirror through total internal reflection. This effect only ...

  5. Plane mirror - Wikipedia

    en.wikipedia.org/wiki/Plane_mirror

    Plane mirrors are the only type of mirror for which an object produces an image that is virtual, erect and of the same size as the object in all cases irrespective of the shape, size and distance from mirror of the object however same is possible for other types of mirror (concave and convex) but only for a specific conditions.

  6. Specular reflection - Wikipedia

    en.wikipedia.org/wiki/Specular_reflection

    A classic example of specular reflection is a mirror, which is specifically designed for specular reflection. In addition to visible light , specular reflection can be observed in the ionospheric reflection of radiowaves and the reflection of radio- or microwave radar signals by flying objects.

  7. Transfer-matrix method (optics) - Wikipedia

    en.wikipedia.org/wiki/Transfer-matrix_method...

    Propagation of a ray through a layer. The transfer-matrix method is a method used in optics and acoustics to analyze the propagation of electromagnetic or acoustic waves through a stratified medium; a stack of thin films.

  8. Cavity optomechanics - Wikipedia

    en.wikipedia.org/wiki/Cavity_optomechanics

    The typical model for many structures in cavity optomechanics is an optical cavity consisting of a fixed mirror and a mechanical oscillator. Cavity optomechanics is a branch of physics which focuses on the interaction between light and mechanical objects on low-energy scales.

  9. Neutron supermirror - Wikipedia

    en.wikipedia.org/wiki/Neutron_supermirror

    A mirror with a larger effective critical angle can be made by exploiting diffraction (with non-zero losses) that occurs from stacked multilayers. [3] The critical angle of total reflection, in degrees, becomes approximately 0.1 ⋅ λ ⋅ m {\displaystyle 0.1\cdot \lambda \cdot m} , where m {\displaystyle m} is the "m-value" relative to ...
