It isn't.... take water for example it isn't "smooth" or "shiny" but has reflective properties
Reflection works best if it is on a smooth shiny surface.
Reflection
spectral
Regular reflection is by a plane and shiny surface while the irregular one is from a rough surface.
Reflections occur when light bounces of a smooth and shiny surface. Glass mirrors have a thin layer of silver on the back so that light is reflected.
Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. This is called specular reflection.
a reflection is formed when rays of light bounces off an object onto a smooth shiny surface (such that light rays are reflected off at the same angles) and reflects off it into our eyes.when the surface is rough there wouldn't be a reflection as lights rays from an object is reflected off the rough surface at different angles and does not enter our eyes
Because it is a metal and can be polished to a smooth shiny surface.

Fetal surface.
A smooth shiny surface.
mirror is made up by a piece of glass and below it, it is coated by Mercury. and as we know, almost all metal has shiny surface, glass has smooth surface which helps the mercury to have total reflection effect. when light is shown, the light is reflected to our eyes, and our eyes detected high intensity of light, we will find it very shiny.
