Light is measured in many units. Its wavelength, λ, is measured in both ...ngstroms and nanometers. Its frequency is measured in Hertz. Its energy is usually measured in electron-volts (eV), since Joules are too large to be practical. Its red-shift is measured in either short-distance...
The Greek letter lambdaλrepresents wavelength, expressed in meters. Thevis wave velocity, calculated as meters per second (m/s). And thefstands for frequency, which is measured in hertz (Hz). For example, iffis the frequency of the signal as measured in megahertz (MHz), andλis the wav...
Torque in a car is measured in nm (newton meters) or ft-lb / lbft / lbf-ft (pounds per foot) - NB people quote torque as lbft, ftlb, lb-ft and ft-lb but these can be regarded as one and the same. All terms will interchange quite safely lbf likewise is fine, although possibly...
Altogether, on average, systolic BP measured by auscultation with a sphygmomanometer variably underestimates intra-arterial brachial systolic BP, systematically overestimates diastolic BP and systematically underestimates pulse pressure. The causes of the cuff discrepancies from intra-arterial BP are not fully...
In a primer limited multiplex reaction, the Ct values for both genes will still be measured accurately. In a typical singleplex TaqMan reaction the primer concentrations are 900nM each and the probe has a concentration of 250nM. In a primer limited assay, the pri...
The whole range of possible wavelengths is called the “spectrum.” Here’s how the spectrum oflighttranslates into the spectrum ofcolor: (MNDNF/Wikipedia) The wavelength of light is measured in nanometers (nm). The longer the wavelength, the “warmer” the color appears. (We’ll talk abou...
Different processes or nodes are differentiated by a length that has historically been measured in micrometers and nanometers, and the lower the number, the better the process (think golf rules). This number used to refer to the physical dimensions of a transistor, which manufacturers want to ...
The center wavelength is the wavelength measured at the midpoint of a half-amplitude line in the transmit spectrum. Lasers of different types or two lasers of the same type may have different center wavelengths due to factors such as techniques and production processes. Even the same laser may...
This is because chip manufacturers are constantly finding new ways to etch transistors onto the silicon. The tiny transistors are now measured in nanometers, which is one billionth of a meter. Atoms themselves are approximately 0.5 nm. The smaller transistors get, the more can be fit onto one...
In conclusion, the term “nm” in CPU specifications refers to the size of the transistors used in their fabrication, measured in nanometers. By embracing smaller nm processes, CPUs can deliver improved performance, power efficiency, reduced heat output, increased transistor density, and future-proo...
