JEE · NEET Previous Year Question
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.
Topic: JEE PYQ
Answer: A. Full step-by-step solution below.
- 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
Solution
(a) 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.
