Draw a neat and labelled diagram of the experimental set-up for observing
the scattering of light in a colloidal solution of sulphur to show how the sky
appears blue and the sun appears red at sunrise and sunset.

Apparatus Required :
Sodium Thio sulphate solution, sulphuric acid and beaker , source of light, convex lens
The source of light is passed at focus of convex lens , so as to produce parallel beam of light rays.
observations :
due to chemical reaction which occurs, we get sulphur as precipitate . we observe the blue colour is scattered due to smaller wavelength of sulphur particles [ view from side of beaker]
If we view it from convex lens L1, source, we see a red patch on screen.mainly because red colour reaches screen after passing through colloidal solution containing sulphur.
