What type of reflection occurs when light reflects off a rough surface?

Specular reflection
Diffuse reflection
Refractive reflection
Angular reflection

The correct answer is: Diffuse reflection

The correct choice is diffuse reflection because this phenomenon occurs when light strikes a rough or uneven surface. Unlike specular reflection, where light reflects at a single angle, diffuse reflection causes light to scatter in many directions due to the microscopic irregularities on the rough surface. This scattering results in a more uniform illumination of the surface, making it visible from various angles without producing clear images, such as would be seen with a smooth, shiny surface. In a real-world context, think of non-glossy surfaces, such as paper or rough walls. When light hits these surfaces, it reflects diffusely, allowing us to see them from different angles rather than having a concentrated beam of light reflecting directly back. This principle is essential in understanding how surfaces interact with light in both natural and artificial environments.
