This experiment demonstrates the linear relationship between the absorbance and the concentration of a colored solution. . UV-VIS Spectroscopy. Ultraviolet and Visible Absorption Spectroscopy. When matter absorbs electromagnetic radiation in the domain ranging from the near ultraviolet to the very near infrared (180-1100nm) it is considered to be UV/Visible.. Properties of Light. Electromagnetic radiation. moves in waves. Electromagnetic Spectrum. Electromagnetic Spectrum. Colors & Wavelengths. COLOR. WAVELENGTH (. λ in nm). Ultraviolet. < 380. Violet. The absorbance (A) is proportional to the concentration (c) of the solution and the Calculated on the basis that is 1 cm and c is 1% w/v solution, the absorbance is called specific absorbanc Figure 1.
