Critical angle, английский
- The angle at which light in a high-refractive-index material undergoes total internal reflection. in geometric optics, at a refractive boundary, the smallest angle of incidence at which total internal reflection occurs.
- An angle of pitch of stairs or a ramp which is considered uncomfortable and unsafe if exceeded; this angle is 50° for stairs and 20° for ramps.
- Incident angle of the ultrasound beam where the refracted beam is parallel to the surface and above which a specific mode of refracted energy no longer exists.
- Угол падения ультразвукового луча, при котором преломленный луч параллелен поверхности и выше которого определенный вид преломленной энергии больше не существует.
- (1) in ultrasonic testing, incident angle of the ultrasound beam where the refracted beam is parallel to the surface and above which a specific mode of refracted energy no longer exists. see also mode conversion.18 (2) in visual testing, incident angle above which total internal reflection occurs. critical angle is key to the operation of fiber optics.
- Incident angle of the ultrasound beam where the refracted beam is parallel to the surface and above which a specific mode of refracted energy no longer exists.7,21
Channel spacing, английский
- The amount of bandwidth allocated per channel.
- Канальный интервал
