write an activity for observing scattering of light in colloidal solution
Answers
Answer:
Take few ML of milk in a transparent glass and dilute it with water to make appreciate cloudy. Now , take a lacer touch and point the beam through the solution. Observe the solution. You will be able to see the path of laser light because of scattering of laser beam by the suspended particles of milk in the solution.
Answer:
(i) Place a strong source of white Light at the f9qqs of the converging lens.
(iii) Allow the light beam to pass through a transparent glass tank containing clear water. In that clear water dissolve 200g sodium, thiosulphate in about 2 L of clean water in the tank and add 1 to2 mLof conc. H2SO4 acid.
(iii) Allow the beam of light to pass through a circular a hole made of a cardboard. Obtain a sharp image of the circular hole on screen by using converging lens
