Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The diameter of colloidal particles in solution should not be much smaller than wavelength of light to show Tyndall effect.
Reason R : The light scatters in all directions when the size of particles is large enough.
In the light of the above statements, choose the correct answer from the options given below:
Solution
Tyndall effect is observed only when the following two conditions are satisfied<br/><br/>
(a) The diameter of the dispersed particle is not much smaller than the wave length of light used.<br/><br/>
(b) Refractive indices of dispersed phase and dispersion medium differ greatly in magnitude.
