The more _____ and _____ the surface of an object is, the more light it reflects.

The correct answer is: Smooth, polished

• If the surface is smooth and shiny, like glass, water, or polished metal, the light will be reflected at the same angle as it hits the surface. This is called specular reflection. Light is reflected at the same angle as it hits a smooth surface.
• The best surfaces for reflecting light are very smooth surfaces such as Glass mirrors or polished metals, although almost all surfaces reflect light to some degree.
