WebMar 16, 2024 · Fourier transform methods are designed in such a way that they record the spectra in the time domain. The plot in Figure 4.3. 8 represents a particular wavelength or frequency of radiation in its time domain. What we observe in the time domain is the oscillation of the amplitude of the wave as a function of time. Figure 4.3.
WebInfrared light is part of the electromagnetic spectrum between visible light and microwaves, with wavelengths ranging from 780 nm to 1 mm. Due to historical reasons however, we typically discuss IR light in spectroscopy in terms of wavenumbers rather than wavelengths. Wavenumbers tell us the number of wavelengths per unit distance and are … title 78Webarranged as 16 individual, gold-wired infrared detector ele-ments.
