TYPE OF REFLECTION?

Specular or the mirror-like reflection

It is a reflection path that occurs when light hits a smooth surface. Light is reflected in a direction opposite to the angle of light incident on the surface of the object. For example, if light shines on the surface of an object at an angle of 50 degrees, the light is reflected at an angle of 130 degrees.

Matte or diffuse

Reflection that occurs when light hits a rough surface. The amount of light that is scattered in several directions and returned to the light source is very small.
The reason it’s usually hard to see at night is when light is shining because diffuse reflection occurs.

Retro-Reflection

Light is reflected off the surface of an object and returned to the light source. It is a logic that reflects light in the direction of the light source no matter what angle it shines. When a vehicle’s headlights or flashlights shine on a material, it reverts to the driver or the person near the light source. The retroreflective function is mainly used for safety equipment such as road signs or reflective safety vests.
