Peak-to-peak amplitude (abbreviated p–p or PtP or PtoP) is the change between peak (highest amplitude value) and trough (lowest amplitude value, which can be negative). With appropriate circuitry, peak-to-peak amplitudes of electric oscillations can be measured by meters or by viewing the waveform on an oscilloscope .
This glossary of physics is a list of definitions of terms and concepts relevant to physics, its sub-disciplines, and related fields, including mechanics, materials science, nuclear physics, particle physics, and thermodynamics.

Scientific terminology is the part of the language that is used by scientists in the context of their professional activities. While studying nature, scientists often encounter or create new material or immaterial objects and concepts and are compelled to name them.
Obsolete name for an ammeter; now an instrument for measuring fluid viscosity. rheostat Obsolete name for a two terminal variable resistor, usually with a rotating shaft to allow manual or motor driven adjustment. right-hand rule A mnemonic device for remembering the definitions of the directions of current and magnetic field in generators. ripple
Sometimes the word is used as a synonym of "wave function" or "pure state". State vector synonymous to "wave function". Statistical ensemble A large number of copies of a system. System A sufficiently isolated part in the universe for investigation. Tensor product of Hilbert space
