Transcript and Presenter's Notes

Title: Egg white


1
Egg white
  • TMF 2004
  • Gymnasium Elišky Krásnohorské

2
Scatter of light
  • white egg doesnt absorb the light of specific
    frequency
  • ? egg is white and white light must be scattered

light source
transmision
white light
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) Meis
    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 Rayleigs 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
    Rayleigs scatter
  • size of particle is size of fluctuation
  • the biggest in critical state

6
Examples
  • Meis scatter
  • colloidal solutions
  • solutions of tenzides (production of micels)
  • body of animals 1)
  • fluctuations scatter
  • sky
  • molecular water solution
