Question

when light hits a smooth, shiny surface like a mirror, it follows a rule called the law of reflection. this rule says that the way light bounces off depends on the angle of incidence. the same is true when it bounces off a rough surface. this works well for smooth surfaces like mirrors.

but if the surface is bumpy or uneven, like your skin or your shirt, things change a bit. the light doesnt bounce off in the same way every time. this is called diffuse reflection, and it makes the reflection pattern less predictable. smooth surfaces follow a clear rule, but on bumpy ones, the light scatters, making it seem like its bouncing off in all directions.

what does the law of reflection say?

the law of reflection says that light travels faster in denser mediums.

the law of reflection states that light changes color when it reflects off a surface.

the law of reflection says the angle of incidence equals the angle of reflection.

Explanation:

The law of reflection is a fundamental principle in optics. It specifically focuses on the relationship between the angle at which light hits a surface (angle of incidence) and the angle at which it bounces off (angle of reflection). The first option about light traveling faster in denser mediums is related to refraction (a different optical phenomenon). The second option about light changing color on reflection is incorrect as reflection doesn't change light's color. The law clearly states the equality of the two angles, which is what the last option describes.

Answer:

The law of reflection says the angle of incidence equals the angle of reflection.
