What occurs during diffuse reflection?

What occurs during diffuse reflection?

• A. Uniform rays reflect straight back
• B. Uniform incoming rays reflect and scatter in all directions
• C. Light rays penetrate the surface
• D. Rays are absorbed completely by a rough surface

Answer: (B)

During diffuse reflection, light rays that strike a rough or uneven surface do not reflect uniformly. Instead, the incoming rays scatter in multiple directions as they bounce off the surface. This scattering occurs because the microscopic imperfections and variations in height on the surface cause the angles of reflection to vary for different parts of the light wave. As a result, the light does not simply reflect straight back, leading to a more diffused and softer illumination of the area. This phenomenon is commonly observed with materials such as paper, wood, or painted surfaces, providing a more uniform brightness rather than a sharp reflection.
