Reflection (physics) 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.

Reflection (mathematics) In mathematics, a reflection (also spelled reflexion) is a mapping from a Euclidean space to itself that is an isometry with a hyperplane as a set of fixed points; this set is called the axis (in dimension 2) or plane (in dimension 3) of reflection. The image of a figure by a reflection is its mirror image in the axis or plane of reflection.

Reflection seismology Reflection seismology (or seismic reflection) is a method of exploration geophysics that uses the principles of seismology to estimate the properties of the Earth 's subsurface from reflected seismic waves.he general principle of seismic reflection is to send elastic waves (using an energy source such as dynamite explosion or Vibroseis) into the Earth, where each layer within the Earth reflects a portion of the wave’s energy back and allows the rest to refract through.

Critical Reflection Critical Reflection. Critical reflection is a reasoning process to make meaning of an experience. Critical reflection is descriptive, analytical, and critical, and can be articulated in a number of ways such as in written form, orally, or as an artistic expression. In short, this process adds depth and breadth to an experience and builds connections between course content and the experience.

- Making the world better, one answer at a time. A reflection is when light beams hit an object that is also giving off light beams. The light beams collide sending them back to our eyes.

Reflection (physics) The law of reflection states that θ i = θ r, or in other words, the angle of incidence equals the angle of reflection. In fact, reflection of light may occur whenever light travels from a medium of a given refractive index into a medium with a different refractive index.

Reflection seismology Reflection seismology (or seismic reflection) is a method of exploration geophysics that uses the principles of seismology to estimate the properties of the Earth 's subsurface from reflected seismic waves.he method requires a controlled seismic source of energy, such as dynamite / Tovex, a specialized air gun or a seismic vibrator, commonly known by the trademark name Vibroseis. Reflection seismology is similar to sonar and echolocation.

- The reflection of light can be roughly categorized into two types of reflection. Specular reflection is defined as light reflected from a smooth surface at a definite angle, whereas diffuse reflection is produced by rough surfaces that tend to reflect light in all directions (as illustrated in Figure 3).

2. Self-reflection Self-reflection is the process of examining the impact of personal values, beliefs, styles of communication, and experiences. This process develops a deeper understanding of one’s culture, personal and cultural biases, experiences, and beliefs as these may influence future action and learning. Self reflection is a process that can be used to maximize personal satisfaction and strengthen MCH commitment.

It produced no single artistic style or characteristic but strongly influenced the ideals of imagination, emotion, and the freedom of expression in other media.

- Total internal reflection in a block of acrylic. Total internal reflection is a phenomenon which occurs when a propagating wave strikes a medium boundary at an angle larger than a particular critical angle with respect to the normal to the surface.he critical angle is the angle of incidence above which the total internal reflection occurs. This is particularly common as an optical phenomenon, where light waves are involved, but it occurs with many types of waves, such as electromagnetic waves in general or sound waves.

- Reflection in a Line. A reflection over line m (notation r m) is a transformation in which each point of the original figure (pre-image) has an image that is the same distance from the reflection line as the original point, but is on the opposite side of the line.

- Reflection Reflection is the abrupt change in the direction of propagation of a wave that strikes the boundary between two different media. At least some part of the incoming wave remains in the same medium. Assume the incoming light ray makes an angle θi with the normal of a plane tangent to the boundary. and T depend on the indices of refraction of the two media n1 and n2, the angle of incidence θ1, and the polarization of the incident light. We distinguish between p-polarization and s-polarization. Let the plane of incidence contain the normal to the boundary and the incident wave vector k1.
