Voltage signals are measured from the amount of light that passes each quartz sample and the values are compared with the wavelengths of the visible spectrum impact. The results show that each substance produces a specific voltage signal in a color range similar to that of the sample and a particular waveform. Both the transmittance and absorbance are identified with the spectrophotometer once the voltage ratio that produces each of the substances in the sample is identified. All the voltages and wavelength generated with each quartz sample testing each color is included in the study.
