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.
- A Both S-I and S-II are correct
- B \(\mathrm{S}-\mathrm{I}\) is correct but S-II is incorrect
- C Both S-I and S-II are incorrect
- D \(\mathrm{S}-\mathrm{I}\) is incorrect but \(\mathrm{S}-\mathrm{II}\) is correct
Answer & Solution
Correct Answer
(A) Both S-I and S-II are correct
Step-by-step Solution
Detailed explanation
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.
