Twinkling effect observed when light from a very small radiating source passes through a turbulent medium
A random fluctuation of the received field strength caused by irregular changes in the transmission path over time
A fluctuation of the amplitude or phase of a radio signal caused by irregular structure of the medium through which it is propagating, like the ionosphere
is the sparkling action associated with the Quickstep's crackling personality - the snappy foot-flicks and jumps that addd energy and joy to this dance or any other dance such as Jive, Samba, etc that exude the same energy and radiance
Effect that can cause loss of returns because of interference of signals from different objects within the same resolvable element causes large random amplitude variation
The emission of light that occurs when electrons or positrons excite a substance in a transparent material they are passing through
When light reflects from a diamond, the sparkling flashes that come from the facets of the gem are known as scintillation Shallow cut Cut refers to the angles and proportions a skilled craftsman creates in transforming a rough diamond into a finished diamond When a diamond is cut too shallow, it will lose or leak light through the side or bottom This results in less brilliance and value
The "twinkling" of a celestial object or the rapid variations in a star's brightness This twinkling is caused by changes of the air temperature in the Earth's atmosphere Changes in air temperature causes turbulence which varies the bending of the light entering the atmosphere
A scintillation counter consists of a material that emits light when radiation passes through it Various liquid, plastic, and crystalline materials have scintillation properties Scintillation light is measured with photomultiplier tubes In general the amount of scintillator light detected is proportional to the energy of the radiation
In electromagnetic wave propagation, a small random fluctuation of the received field strength about its mean value (188) Note: Scintillation effects become more significant as the frequency of the propagating wave increases
the twinkling of the stars caused when changes in the density of the earth's atmosphere produce uneven refraction of starlight a brilliant display of wit (physics) a flash of light that is produced in a phosphor when it absorbs a photon or ionizing particle
