   6. Amplitude of the range of a projectile, denotes the horizontal line subtending the path in which it moved.7. Amplitude, in astronomy, an arch of the horizon, intercepted between the true east and west point thereof, and the centre of the sun or star at its rising or setting. It is eastern or ortive, when the star rises, and western or occiduous, when the star sets. The eastern or western amplitude, are also called northern or southern, as they fall in the northern or southern quarters of the horizon.8. Magnetical amplitude,is an arch of the horizon contained between the sun at his rising, and the east or west point of the compass; or, it is the difference of the rising or setting of the sun, from the east or west parts of the compass.

1. Amplitude

   The amplitude of a periodic variable is a measure of its change in a single period (such as time or spatial period). The amplitude of a non-periodic signal is its magnitude compared with a reference value. There are various definitions of amplitude (see below), which are all functions of the magnitude of the differences between the variable's extreme values. In older texts, the phase of a periodic function is sometimes called the amplitude.

1. amplitude

   Amplitude is the maximum extent of a periodic oscillation, vibration, or wave, measured from the position of equilibrium. It is often used to describe the magnitude or intensity of phenomena such as sound, light and electronic signals.

1. Amplitudenoun

   state of being ample; extent of surface or space; largeness of dimensions; size

2. Amplitudenoun

   largeness, in a figurative sense; breadth; abundance; fullness

3. Amplitudenoun

5. Amplitudenoun

   the arc of the horizon between the true east or west point and the center of the sun, or a star, at its rising or setting. At the rising, the amplitude is eastern or ortive: at the setting, it is western, occiduous, or occasive. It is also northern or southern, when north or south of the equator

6. Amplitudenoun

1. amplitude

   As a general term, implies extent. In astronomy, it is an arc of the horizon intercepted between the true east or west points thereof, and the centre of the sun, star, or planet, at its rising or setting. In other words, it is the horizontal angular distance of a star from the east or west points. It is eastern or ortive when the heavenly object rises, and western or occiduous when it sets, and is moreover northern or southern according to its quarter of the horizon.--Amplitude, in gunnery, is the range or whole distance of a projectile, or the right horizontal line subtending the curvilineal path in which it moved.--Amplitude, in magnetism, is the difference between the rising and setting of the sun from the east and west points, as indicated by the mariner's or magnetic compass--which subtracted from the true amplitude, constitutes the error of the compass, which is the combined effect of variation and local deviation.

Examples of amplitude in a Sentence

1. Rebecca Robbins:

   If Joshua Tal're practicing some of these activities, what we do see is( an) increase in the amplitude of theta and delta( brain) waves, which indicate one is in the parasympathetic state, slow breathing like the 4-7-8 technique reduces the risk of cardiovascular disease and type 2 diabetes and improves pulmonary function.

2. Mario Damasso:

   In my opinion, the detection is particularly interesting because the signal in the radial velocities has a low amplitude and a long period, therefore in principle not easy to detect and confirm with a single technique, we are exploring the consequences of a longer-term spectroscopic follow-up in another work we hope to publish soon.

3. Kyle Theim:

   The warm, smothering embrace of a high-amplitude ridge will continue into the long term period, temperatures starting on Monday will run between 10-15 degrees above normal, and border on record maximum temperatures, both for daily highs and lows.

4. Stephen Jay Gould:

   The true beauty of nature is her amplitude she exists neither for nor because of us, and possesses a staying power that all our nuclear arsenals cannot threaten (much as we can easily destroy our puny selves).

5. Julie Cote:

   So the results of this study when we measured muscle activity in walking we show lower muscle activity amplitude, we show more variable muscle activity patterns and we show less co-activation all with no impact on productivity on the typing performance.
