Correct Answer: be scattered


Solution : The correct option is be scattered.

A strong beam of light is dispersed when it passes through a colloidal solution. The Tyndall effect was named after the 19th-century scientist John Tyndall, who first observed it. The Tyndall effect happens when light collides with colloidal particles floating in a media (typically a liquid or gas) that are big enough to disperse the light but small enough to avoid gravity's pull. The scattered light appears as a cone or beam of light as a result of the colloidal particles dispersing the incident light.
