Write answers in one sentence each :
Why does colloidal particle show Tyndall effect

Explanation

**Step-by-Step Text Solution:**

1. **Understanding Colloidal Particles:** Colloidal particles are small particles that are dispersed in a medium, and their size typically ranges from 1 nanometer to 1000 nanometers.

2. **Tyndall Effect Definition:** The Tyndall effect refers to the scattering of light by particles in a colloid or in very fine suspensions.

3. **Size Comparison:** The diameter of colloidal particles is comparable to the wavelength of visible light, which is approximately 400 to 700 nanometers.
