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.
Options
- ABoth S-I and S-II are correct
- BS - I is correct but S-II is incorrect
- CBoth S-I and S-II are incorrect
- DS - I is incorrect but S - II is correct
Correct answer
A. Both S-I and S-II are correct
Step-by-step 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.
