The definitons of the transform (to expansion coefficients) and the inverse transform are given below: halloween stickers clipartOne of the most basic tasks in spectroscopy is to characterize the spectrum of a light source: how much light is emitted at each different wavelength. The most straightforward way to measure a spectrum is to pass the light through a monochromator, an instrument that blocks all of the light except the light at a certain wavelength (the un-blocked wavelength is set by a knob on the monoch… halloween stickers for the windowThe Fourier transform is analogous to decomposing the sound of a musical chord into terms of the intensity of its constituent pitches. The red sinusoid can be described by peak amplitude (1), peak-to-peak (2), RMS (3), and wavelength (4). The red and blue sinusoids have a phase difference of θ.
