  2. Glossary of physics - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_physics

    The natural science that involves the study of matter and its motion through space and time, along with related concepts such as energy and force. More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves. piezoelectricity pion Planck constant Also called Planck's constant.

  3. Crest and trough - Wikipedia

    en.wikipedia.org/wiki/Crest_and_trough

    Crest and trough in a wave. A Crest point on a wave is the highest point of the wave. A crest is a point on a surface wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point of the wave.

    en.wikipedia.org/wiki/Scientific_terminology

    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.

    amplitude: meter: atomic mass number: unitless acceleration: meter per second squared (m/s 2) magnetic flux density also called the magnetic field density or magnetic induction tesla (T), or equivalently, weber per square meter (Wb/m 2) capacitance: farad (F) heat capacity

    The periodic summation has been reduced in amplitude and periodicity by a factor of M. An example of both these distributions is depicted in the two traces of Fig 1. [e] [f] [g] Aliasing occurs when adjacent copies of X(f) overlap. The purpose of the anti-aliasing filter is to ensure that the reduced periodicity does not create overlap.

  7. Amplitude - Wikipedia

    en.wikipedia.org/wiki/Amplitude

    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 .

    Amplitude is a measure of a periodic variable in classical physics. Amplitude may also refer to: In mathematics and physics. Jacobi amplitude of Jacobi ...

  9. Attenuation - Wikipedia

    en.wikipedia.org/wiki/Attenuation

    Attenuation in ultrasound is the reduction in amplitude of the ultrasound beam as a function of distance through the imaging medium. Accounting for attenuation effects in ultrasound is important because a reduced signal amplitude can affect the quality of the image produced.
