A light ray strikes a rough surface. What is the most likely behavior of the light after striking the surface?
Understand the Problem
The question asks about the most likely behavior of a light ray when it encounters a rough surface. This involves understanding the concept of reflection, specifically diffuse reflection, and how surface texture affects the way light is reflected.
Answer
The light will undergo diffuse reflection.
When a light ray strikes a rough surface, it will most likely undergo diffuse reflection, scattering the light in many directions due to the surface irregularities.
Answer for screen readers
When a light ray strikes a rough surface, it will most likely undergo diffuse reflection, scattering the light in many directions due to the surface irregularities.
More Information
Diffuse reflection is responsible for why we can see objects from various angles. If surfaces were perfectly smooth, light would only reflect in one direction, making it difficult to see.
Tips
A common mistake is thinking light only bounces 'straight back' from a surface. Roughness causes scattering, not a single, direct reflection.
