INSTRUMENTAL Scintillation is a flash or sparkle of light Example: Scintillations of diamond-hard light. Else It's a process or state of emitting flashes of light. In physics it's a small flash visible or Ultraviolet light emitted by fluorescence in a phosphor When struck by a charged particle or high-energy proton. Elaboration 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
