What does scintillation mean?
Definition of scintillation 1 : an act or instance of scintillating especially : rapid changes in the brightness of a celestial body. 2a : a spark or flash emitted in scintillating. b : a flash of light produced in a phosphor by an ionizing event.
What is meant by scintillation spectrometer?
Definition of scintillation spectrometer : an apparatus in which mass or energy spectra are observed and their frequency distribution determined by means of a scintillation counter.
What is scintillation in astronomy?
Scintillation, the “twinkling” of stars to the unaided eye, is a commonly known result of turbulence in the higher reaches of the atmosphere. Poor seeing in telescopes is more a result of turbulence in the lower atmosphere.
What is scintillation effect?
Scintillation of radio waves impacts the power and phase of the radio signal. Scintillation is caused by small-scale (tens of meters to tens of km) structure in the ionospheric electron density along the signal path and is the result of interference of refracted and/or diffracted (scattered) waves.
What is scintillation in chemistry?
Scintillation is a flash of light produced in a transparent material by the passage of a particle (an electron, an alpha particle, an ion, or a high-energy photon).
What is a scintillator used for?
Scintillators are materials that are able to convert high energy radiation such as X or gamma-rays to a near visible or visible light. They are widely used as detectors in medical diagnostics, high energy physics and geophysical exploration (ref.
What is scintillator in physics?
Scintillation is a flash of light produced in a transparent material by the passage of a particle (an electron, an alpha particle, an ion, or a high-energy photon). See scintillator and scintillation counter for practical applications.
What is scintillation Class 12?
Scintillation Counter is an instrument that is used for measuring ionizing radiation. “It comprises the scintillator that generates photons in response to incident radiation”, a PMT tube is used to convert an electronics and electric signal to process the signal.
What is R in math?
In maths, the letter R denotes the set of all real numbers. That means, R = {-⅔, 8, 0, ¼, – 5, -100, 234,…….} Real numbers are the numbers that include, natural numbers, whole numbers, integers, and decimal numbers. In other words, real numbers are defined as the points on an infinitely extended line.
