The Tyndall effect is the scattering of light as a light beam passes through a colloid. The individual suspension particles scatter and reflect light, making the beam visible. Milk, tincture iodine, and the white part of the egg show the Tyndall effect whereas salt solution did not show the Tyndall effect.

Explanation:
The Tyndall effect is the scattering of light by colloidal particles or very fine particles in a transparent medium. When a beam of light passes through a medium and encounters particles, the light scatters in all directions. This scattering of light is what we observe as the Tyndall effect.
To determine which of the given options do not show the Tyndall effect, let's consider each option one by one:
A. Milk:
Milk is a colloidal suspension of fat globules and protein particles in water. These particles are large enough to scatter light and therefore exhibit the Tyndall effect. So, milk shows the Tyndall effect.
B. The White part of the egg:
The white part of the egg, also known as egg white or albumen, is a colloidal solution. It contains proteins dissolved in water. Similar to milk, the particles in egg white are also large enough to scatter light, resulting in the Tyndall effect. So, the white part of the egg shows the Tyndall effect.
C. Tincture iodine:
Tincture iodine is a solution of iodine in alcohol or water. Unlike milk and egg white, tincture iodine does not contain particles large enough to scatter light. Therefore, it does not show the Tyndall effect.
D. Salt solution:
Salt solution is a homogeneous mixture of salt dissolved in water. It does not contain any particles that are large enough to scatter light. Therefore, salt solution does not show the Tyndall effect.
Conclusion:
Based on the above analysis, the option that does not show the Tyndall effect is C. Only D (Salt solution).
