  1. Egg white TMF 2004 Gymnasium Elišky Krásnohorské

  2. Scatter of light • white egg doesn`t absorb the light of specific frequency  egg is white and white light must be scattered light source white light transmision sample detector scatter detector

  3. Colour of light • colour of light depends on his frequency • quantity of scattered light can depend on his frequency (wave lenght) lower frequency higher

  4. Centers of scatter • small particles (phasic interface) – Mei`s scatter • dependences of quantity scattered light: frequency: I f 4 size of particle: I V2  red and orange light is fewer scattered  output light is ruddier So-called Rayleig`s scatter - size of particle must be to 0,1 wave length of light

  5. Centers of scatter • fluctuation of concentration • dependence of quantity scattered light is like Rayleig`s scatter • size of particle is size of fluctuation • the biggest in critical state

  6. Examples • Mei`s scatter • colloidal solutions • solutions of tenzides (production of micels) • body of animals 1) • fluctuation`s scatter • sky • molecular water solution • 1) Greenewalt C.H.: Hummingbirds. Doubleday & Company, Inc., New York 1960, page 169
