Product description

14 Construct a gauge Geller curve in coordinates α = f (d) for particles of polystyrene latex:
d, nm 77.0 88.0 95.0 106.7 111.0 119.0 132.0 139.0
α 3.82 3.64 3.54 3.30 3.23 3.04 2.82 2.72
Determine the average radius of particles of polystyrene latex, based on the following experimental data:
The wavelength λ, nm 415 485 527 685
Optical density D 0.195 0.127 0.099 0.048
