Li and Hua 13, utilizing the spectral finite aspect method arrived at numerical options for natural frequencies of the 2 elastically connected Timoshenko beams with totally different helps. The alternating mild indicators, from both the reference beam or pattern beam generate alternating electrical phototransducer indicators. A double beam spectrophotometer compares the light depth between two gentle paths, one path containing a reference sample and the other the test sample. Remember that since the reference cell does not have any gentle absorbing analyte, the light exiting the reference cell will at all times be brighter than that from the pattern cell even if the solvent itself absorbs some at the analyte wavelength since each cuvettes contain solvent. The noticed absorbance measurement is the ratio of the sample and reference beams which are recombined before moving to the monochromator.
