Rough and opaque surfaces are characteristics of poor reflectors of light. Such surfaces cause the light waves to scatter. Therefore, substances that could be listed on the "good reflectors" side of your table are: metals (aluminum, copper, silver, gold, spoons, etc) and mirrors.
Considering this, what are some objects that reflect light?
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.
What is the reflective material?
Reflective material used on clothes has tiny glass beads embedded on the surface. Each bead is a rounded mirror that shines light back directly to its source – regardless of the angle which the light shines. A car's driver can see a person wearing reflective material even if they are not in front of them.
