reflection: The return of radiant energy (incident light) by a surface, with no change in wavelength
reflection: See Reflex action, under Reflex
reflection: The abrupt change in direction of a wave front at an interface between two dissimilar media so that the wave front returns into the medium from which it originated Note 1: Reflection may be specular (i e , mirror-like) or diffuse (i e , not retaining the image, only the energy) according to the nature of the interface Note 2: Depending on the nature of the interface, i e , dielectric-conductor or dielectric-dielectric, the phase of the reflected wave may or may not be inverted
reflection: the act of reflecting or the state of being reflected
reflection: Reflection is the process by which light and heat are sent back from a surface and do not pass through it. the reflection of a beam of light off a mirror
reflection: The reverting of the mind to that which has already occupied it; continued consideration; meditation; contemplation; hence, also, that operation or power of the mind by which it is conscious of its own acts or states; the capacity for judging rationally, especially in view of a moral rule or standard
reflection: when light or sound waves bounce off a surface and may return to the source; if surface is a plane then the angle of reflection is also the angle of incidence
reflection: the property of a propagated wave being thrown back from a surface (such as a mirror)
reflection: Shining; brightness, as of the sun
reflection: Result of meditation; thought or opinion after attentive consideration or contemplation; especially, thoughts suggested by truth
reflection: Reflection is careful thought about a particular subject. Your reflections are your thoughts about a particular subject. After days of reflection she decided to write back If someone admits or accepts something on reflection, they admit or accept it after having thought carefully about it. On reflection, he says, he very much regrets the comments. Change in the direction of propagation of a wave that strikes a boundary between different media through which it cannot pass. When a wave strikes such a boundary it bounces back, or is reflected, just as a ball bounces off the floor. The angle of incidence is the angle between the path of the wave and a line perpendicular to the boundary. The angle of reflection is the angle between the same line and the path of the reflected wave. All reflected waves obey the law of reflection, which states that the angle of reflection is equal to the angle of incidence. The reflectivity of a material is the fraction of energy of the oncoming wave that is reflected by it
reflection: the phenomenon of a propagating wave (light or sound) being thrown back from a surface
reflection: Radio waves are reflected by conductive surfaces, much as light is reflected by a mirror Reflections can also occur in conductors carrying RF signals when there is an impedance mismatch
reflection: Also called Back Reflection The abrupt change in direction of a light beam at an interface between two dissimilar media so that the light beam returns into the medium from which it originated Reflection from a smooth surface is termed specular, whereas reflection from a rough surface is termed diffuse The higher the associate value, the better the performance expressed in dB Also, see Return Loss

reflection: A reflection is an image that you can see in a mirror or in glass or water. Meg stared at her reflection in the bedroom mirror
reflection: (mathematics) a transformation in which the direction of one axis is reversed
reflection: contemplation: a calm lengthy intent consideration
reflection: The energy or wave from an earthquake that has been returned (reflected) from an boundary between two different materials within the earth, just as a mirror reflects light
reflection: A process that occurs when a propagating electromagnetic wave impinges upon a obstruction whose dimensions are very large when compared to the wavelength Reflections from the surface of the earth, and from buildings or walls produce reflected waves which may interfere, constructively of destructively at the receiver
reflection: An image given back from a reflecting surface; a reflected counterpart
reflection: the ability to reflect beams or rays the phenomenon of a propagating wave (light or sound) being thrown back from a surface (mathematics) a transformation in which the direction of one axis is reversed
reflection: Return of radiation by a surface without a change of frequency

reflection: The reflection through a line in the plane or a plane in space is the transformation that takes each point in the plane to its mirror image with respect to the line or its mirror image with respect to the plane in space It produces a mirror image of a geometric figure
reflection: Contemplation and consideration regarding the significance of the community service work performed; evaluation of the value and meaning of the specific community service as it relates to a larger context Reflection can take place on an individual or group basis and connect community service to one's community, one's values and the impact it has on both the individual performing the work, as well as the larger society Topic areas: Volunteer Management

reflection: it is related that Pythagoras could write what he placed on a glass, and, by the reflection of the same species, would make those letters appear upon the circle of the moon, so plain as to be read by any person, some miles distant from him Cornelius Agrippa affirms the possibility of it, and that the method of performing it was known to himsself and others
reflection: The act of reflecting, or turning or sending back, or the state of being reflected
reflection: If you say that something is a reflection of a particular person's attitude or of a situation, you mean that it is caused by that attitude or situation and therefore reveals something about it.

reflection: A phenomenon that occurs when waves strike barriers or other media In the case of barriers, waves will "bounce" off of the barrier in a direction that is constent with the Law of Reflection In the case of a change in medium, some of the wave reflects while the rest moves into the new medium (see refraction) Here is a simple reflection movie Back to Top Back to Wave Index
