The scattering of beam of light when light passes through a colloidal solution is ………………. 

Correct Answer - (i)4x-y=27=0 (ii)3x+y+3=0 (iii)`sqrt3+y-2=0`

C) A is true but R is false

(A) moves towards the glass slab.

Correct option is B) Colloid

A) air is colloid

a1 = 1.5 a2 To find: \(\frac{I_1}{I-2}\) Formula: I ∝ a2 Calculation: From formula, \(\frac{I_1}{I_2}=(\frac{a_1}{a_2})^2=(\frac{1.5_{a_2}}{a_2})^2\) = (1.5)2 = 2.25

a1 = 2.5 a2 To find: \(\frac{I_1}{I-2}\) Formula: I ∝ a2 Calculation: From formula, \(\frac{I_1}{I_2}=(\frac{a_1}{a_2})^2=(\frac{2.5_{a2}}{a_2})\) = (2.5)2 = 6.25

Correct option is D) gold foil

1. Scattering of light by the colloidal particles takes place and the path of light become illuminated. This is called Tyndall effect. 2. The positively charged colloidal particles of Fe(OH)3 sol...

Correct Answer - A `I_(2)= (I_(0))/(2)cos^(2)theta`
