Options

  1. AThe diameter of dispersed particles is much smaller than the wavelength of light
  2. BThe refractive indices of dispersed phase and dispersion medium are similar
  3. CThe dispersion medium is opaque
  4. DThe refractive indices of dispersed phase and dispersion medium differ greatly in magnitude

Correct answer

D. The refractive indices of dispersed phase and dispersion medium differ greatly in magnitude

Step-by-step solution

According to the paragraph, the Tyndall effect is observed when the refractive indices of the dispersed phase and dispersion medium differ greatly in magnitude.
