Q. Tyndall effect is:

A
Scattering of light by colloidal particle
B
Refraction of light by colloidal particle
C
Absorption of light by colloidal particle
D
Reflection of light by colloidal particle
Solution:
  • The Tyndall effect is the scattering of light as a light beam passes through a colloid.
  • The individual suspension particles scatter & reflect light, making the beam visible.
  • Particles of suspension almost completely reflects the light falling on them due to its bigger size.
  • Particles of solution are very minute, they cannot scatter a beam of light.
