    @metaltao Yes, there are 3 types of reflection

    Specular: Light is directly reflected at an opposite angle off a smooth surface
    Diffused: Light is scattered in all directions off a rough surface
    Spread: Combination of the previous two

    Refraction is none if these, and is just light changing the direction from the light entering a different medium and having its speed changed. Refraction is different from reflection. The moon mainly uses specular reflection to send light to Earth.
