Light bounces exactly back in the direction from which it came due to a nonlinear optical process. In this type of reflection, not only the direction of the light is reversed, but the actual wavefronts are reversed as well. A conjugate reflector can be used to remove aberrations from a beam by reflecting it and then passing the reflection through the aberrating optics a second time.

====Neutron reflection====

====Neutron reflection====

Materials that reflect [[neutron]]s, for example beryllium, are used in nuclear reactors. In the physical and biological sciences, the reflection of neutrons off atoms within a material is commonly used to determine its internal structures.

====Sound reflection====

====Sound reflection====

When a longitudinal [[sound wave]] strikes a flat surface, sound is reflected in a coherent manner provided that the dimension of the reflective surface is large compared to the wavelength of the sound. Note that audible sound has a very wide frequency range (from 20 to about 17000 Hz), and thus a very wide range of wavelengths (from about 20 mm to 17 m). As a result, the overall nature of the reflection varies according to the texture and structure of the surface. For example, porous materials will absorb some energy, and rough materials (where rough is relative to the wavelength) tend to reflect in many directions — to scatter the energy, rather than to reflect it coherently. This leads into the field of [[architectural acoustics]], because the nature of these reflections is critical to the auditory feel of a space.

==== Phenomenological psychology ====

The concepts of phenomenological philosophy have influenced at least two main fields of contemporary psychology: the qualitative psychology of Giorgi, Smith [http://en.wikipedia.org/wiki/Interpretative_Phenomenological_Analysis], Kvale, and others; and the experimental approaches associated with Varela, Gallagher, Thompson, and others [http://en.wikipedia.org/wiki/Embodied_cognition].

===Psychotherapy and the phenomenology of emotion===

===Psychotherapy and the phenomenology of emotion===

[[Carl Rogers]]' person-centered psychotherapy theory is based directly on the "phenomenal field" personality theory of Combs and Snygg (1949). That theory in turn was grounded in phenomenological thinking. [http://webspace.ship.edu/cgboer/snygg&combs.html]. Rogers attempts to put a therapist in closer contact with a person by listening to the person's report of their recent subjective experiences, especially emotions of which the person is not fully aware. For example, in relationships the problem at hand is often not based around what actually happened, but instead is based around the perceptions and feelings of each individual in the relationship. The phenomenal field focuses on "how one feels right now".

Introspections (also referred to as internal [[dialogue]], interior monologue, self-talk) is the fiction-writing mode used to convey a character's thoughts.  As explained by Renni Browne and Dave King, "One of the great gifts of literature is that it allows for the expression of unexpressed thoughts…".  A  character's thoughts can greatly enhance a story: deepening characterization, increasing tension, and widening the scope of a story.  Thought plays a critical role in both scene and sequel.  Among authors and writing coaches, there appears to be little consensus regarding the importance of introspection [http://www.helium.com/tm/624520/introspection-thinking-fiction-writing Fiction writing: The importance of your characters thoughts - Thoughts on Writing - Helium - by Mike Klaassen] and how it is best presented.[http://www.helium.com/tm/614947/mechanics-introspection-fiction-writing Fiction writing: How to write your characters thoughts - Writing Tips - Helium - by Mike Klaassen]
