Given below are two statements (S-I and S-II)
S-I: Scattering of light by dispersed particles of colloidal system is known as Tyndall effect.
S-II: The diameter of the dispersed particles should not be much smaller than the wavelength of the light used.
Choose the most appropriate answer from the options given below.
Both S-I and S-II are correct
$\mathrm{S}-\mathrm{I}$ is correct but S-II is incorrect
Both S-I and S-II are incorrect
$\mathrm{S}-\mathrm{I}$ is incorrect but $\mathrm{S}-\mathrm{II}$ is correct
Solution
Tyndall effect is a characteristic of colloidal particles which scatter light if the size of the particles is similar to the wavelength of the light.
Thus, both statements are correct.
