<P> The Tyndall effect , also known as Willis -- Tyndall scattering , is light scattering by particles in a colloid or else particles in a very fine suspension . It is named after the 19th - century physicist John Tyndall . It is similar to Rayleigh scattering , in that the intensity of the scattered light depends on the fourth power of the frequency , so blue light is scattered much more strongly than red light . An example in everyday life is the blue colour sometimes seen in the smoke emitted by motorcycles , in particular two - stroke machines where the burnt engine oil provides these particles . </P>
