2. When studying the attenuation of blue light by mastic sols, the following data were obtained:
Sol concentration, % 0.6 0.2 0.08 0.04
Layer thickness, mm 2.5 2.5 20 20
Share of transmitted light, % 3.1 30.9 2.6 15.9
Show the applicability of the Bouguer-Lambert-Beer equation for this disperse system. Calculate what proportion of light will be scattered by 0.75% sol with an absorbing layer thickness of 1 mm.
