1 microsecond – the length of time of a high-speed, commercial strobe light flash (see air-gap flash). 1 microsecond – protein folding takes place on the order of microseconds (thus this is the speed of carbon-based life). 1.8 microseconds – the amount of time subtracted from the Earth's day as a result of the 2011 Japanese earthquake.

[7] 43 as: The shortest X-ray laser pulse [8] 53 as: The shortest electron laser pulse [9] [10] 10 −15: femtosecond: fs One quadrillionth of one second 1 fs: The cycle time for ultraviolet light with a wavelength of 300 nanometres; The time it takes light to travel a distance of 0.3 micrometres (μm). 7.58fs: The period of vibration of a ...
1/1000 d (0.001 d) 1.44 minutes, or 86.4 seconds. Also marketed as a ".beat" by the Swatch corporation. moment: 1/40 solar hour (90 s on average) Medieval unit of time used by astronomers to compute astronomical movements, length varies with the season. [4] Also colloquially refers to a brief period of time. centiday 0.01 d (1 % of a day)
The rapid-fire computer-based HFT developed gradually since 1983 after NASDAQ introduced a purely electronic form of trading. [21] At the turn of the 21st century, HFT trades had an execution time of several seconds, whereas by 2010 this had decreased to milli- and even microseconds. [22]
The rise of high-frequency and quantitative trading is both an extreme manifestation of and a contributing factor to a stock market in which the bulk of activity is short-term oriented. It has ...
0.001 s A millisecond (from milli- and second ; symbol: ms ) is a unit of time in the International System of Units equal to one thousandth (0.001 or 10 −3 or 1 / 1000 ) of a second [ 1 ] [ 2 ] or 1000 microseconds .
The magnitude response of a band-pass filter illustrating the concept of −3 dB bandwidth at a gain of approximately 0.707 In some contexts, the signal bandwidth in hertz refers to the frequency range in which the signal's spectral density (in W/Hz or V 2 /Hz) is nonzero or above a small threshold value.
This corresponds to a wavelength of 0.3 mm, as can be calculated by multiplying 1 ps by the speed of light (approximately 3 x 10 8 m/s) to determine the distance traveled. 1 THz is in the far infrared. 1 picosecond – time taken by light in vacuum to travel approximately 0.30 mm; 1 picosecond – half-life of a bottom quark
