Specific acoustic impedence (ut)
| Глоссарий терминов по технологиям неразрушающего контроля (NDT) |
A factor that determines the amount of reflection that occurs at an interface and represents the product of the density of the medium in which the wave is propagating and the wave velocity.

Reflection, английский
- The abrupt change in direction of a light beam at an interface between two dissimilar media that returns the beam into the medium where it originated, i.e., a mirror
- A light ray incident on an air to glass interface will have some of its energy redirected back toward its origin due to reflection at the interface.
- The return of radiant energy (incident light) by a surface, with no change in wavelength.
- The bouncing off of light which falls upon a surface.
- The change of direction which a ray of light, sound, or radiant heat undergoes when it strikes a surface; also
- 1. the image of somebody or something which is seen in a mirror or still water 2. the process of reflecting something, especially light, sound or heat 3. careful thought 4. a situation in which an anatomical structure bends back upon itself
- The process of obtaining information about assemblies and the types defined within them, and creating, invoking, and accessing type instances at run time.
- When light bounces back from a surface
- General term for the process by which the incident energy leaves a surface or medium from the incident side, without change in frequency. reflection is usually a combination of specular and diffuse reflection.2,6
- General term for the process by which the incident energy leaves a surface or medium from the incident side, without change in frequency. reflection is usually a combination of specular and diffuse reflection (iesna 1984). see also diffuse reflection; specular reflection.
- The act of thinking deeply about one`s actions, behaviour`s, and progress, often facilitated by a coach or mentor to promote self-awareness and learning.

Color-contrast dye (pt), английский
A dye which can be used in a penetrant to impart sufficient color intensity to give good color contrast in indications against the background of the surface being tested, when viewed under white light.
