Spectral analysis (see spectroscopy) involves measuring the intensity of the radiation as a function of wavelength or frequency.
Also in the 1950's, Dr. Babcock and his father, Harold, who was at Mount Wilson as well, created the first solar magnetograph for measuring the intensity, direction and distribution of the Sun's magnetic field.
If electrical energy in the form of a spark or an arc is used to excite the analyte prior to measuring the intensity of emitted radiation, the method is atomic emission spectrometry.
The calibration curves were obtained by measuring the intensity after consecutives additions of H2O2 known concentrations.
This law in turn provides a method for indirectly measuring the intensity of sensation by measuring the intensity of the stimulus, and hence, Fechner argued, provides justification for measuring intensities of sensation on the real numbers.
ICP-OES analysis was performed by measuring the intensity of radiation of the specific wavelengths emitted by each element.
The degree of functionalization and imperfections can be estimated by measuring the intensity ratio (ID/IG) of the D and G-band of the nanotubes [12].
Information on drying kinetics was obtained by measuring the intensity of 1H NMR signal as a function of the thickness of the sample.
The polarization state of the scattered light e ^ s is analyzed by measuring the intensity of the two components (parallel or perpendicular to the wire).
As an index measuring the intensity of global geomagnetic activity, the planetary 3-hour-range index Kp has been widely used in ionospheric and geomagnetic fields.
The concentrations of MOX and CEF were calculated from their corresponding regression equations measuring the intensity of signals at 359.3 nm and 269.6 nm respectively.
