The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Colloidal Solution:** - A colloidal solution consists of tiny particles that are dispersed throughout a medium. These particles are larger than molecules but smaller than those in a suspension. 2. **Passing a Beam of Light:** - When a strong beam of light is directed through a colloidal solution, the light interacts with the colloidal particles present in the solution. 3. **Scattering of Light:** - The colloidal particles scatter the light in different directions. This scattering occurs because the size of the colloidal particles is comparable to the wavelength of visible light. 4. **Observation of the Tyndall Effect:** - The scattering of light makes the path of the beam visible. This phenomenon is known as the Tyndall effect. It is a characteristic property of colloidal solutions. 5. **Examples of Tyndall Effect:** - A common example of the Tyndall effect is observed when a beam of light passes through a glass of milk. The fat globules and proteins in the milk scatter the light, making the path of the light beam visible. 6. **Conclusion:** - Therefore, when a strong beam of light is passed through a colloidal solution, the light will be scattered, demonstrating the Tyndall effect. **Final Answer:** When a strong beam of light is passed through a colloidal solution, the light will be scattered. This phenomenon is known as the Tyndall effect. ---
