Objects that reflect well are

• Matte surfaces

• Smooth, shiny surfaces

• Dark coloured surfaces

• Medium coloured surfaces

The law of reflection states that

• Angle of incidence = Angle of reflection

• Angle of incidence = Angle of incidence

• Angle of reflection = Angle of translucence

• Angle of reflection = Angle of reflection

Refraction is

• The bending of light as it passes through the one substance at an angle

• A light beam shone in one end of an optical fibre and totally internally reflected at the other end

• The bending of light as it passes from one substance to another at an angle

• A type of convex object used in everyday life
