Storng Tyndall effect is observed only when  (i) the refractive indices of the dispersed phase and the dispersion medium differ greatly in magnitude (ii) the diameter of the dispersed particles is biggest than the wavelength of the light used  (iii) the refractive indices of the dispersed phase and the dispersion medium are similar  (iv) the diameter of the dispersed particles is not much smaller than the wavelength of the light used
