The light that is scattered by particles in the unknown solution is measured and made as a basis of determining its concentration.

Factors affecting the amount of light scattered are:

a.the wavelength used – dispersion of light is inversely proportional to the
b.the size of the particles
c.the amount of particles in solution
d.the cross sectional area of the particles
e.the source of light - monochromatic lights give more reliable readings because they
minimize sample heating and have more stable readings.
