Question

when light hits a smooth, shiny surface like a mirror, it follows a simple rule called the law of reflection. this rule states that however light comes in (angle of incidence), it bounces off in the same way (angle of reflection). this works well on smooth surfaces like mirrors. but, if the surface is bumpy or uneven (like a rough wall or paper), things change a bit. the light doesnt bounce off in the same way everywhere. this is called diffuse reflection, and it makes the reflection softer and less predictable. smooth surfaces follow a clear rule, but on bumpy ones, the light scatters, resulting in a less straightforward reflection in those cases. what is the term for the angle at which light comes in before reflecting, as shown in the image (angle a)? angle of incidence angle of reflection angle of diffusion

Explanation:

The angle at which light comes in before reflecting is defined as the angle of incidence. This is a fundamental concept in the study of light reflection.

Answer:

Angle of incidence
