The spark micrometer, also known as a Riess micrometer [1] was a device used by 19th century physicists to measure potential in an electric circuit. It was developed principally by German physicist Peter Riess .

The equivalent width of a spectral line is a measure of the area of the line on a plot of intensity versus wavelength in relation to underlying continuum level. It is found by forming a rectangle with a height equal to that of continuum emission, and finding the width such that the area of the rectangle is equal to the area in the spectral line.
Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a metal fabrication process whereby a desired shape is obtained by using electrical discharges (sparks). [1]
In a distribution, full width at half maximum (FWHM) is the difference between the two values of the independent variable at which the dependent variable is equal to half of its maximum value. In other words, it is the width of a spectrum curve measured between those points on the y -axis which are half the maximum amplitude.

This is true independent of the value of since the equation for + is not needed to calculate the value of at points and . 3D centripetal Catmull-Rom spline segment. The extension to 3D points is simply achieved by considering P i = [ x i y i z i ] T {\displaystyle \mathbf {P} _{i}=[x_{i}\quad y_{i}\quad z_{i}]^{T}} a generic 3D point P i ...
