Electromagnetic waves are reflected

Explanation:

Reflection of light (and other forms of electromagnetic radiation) occurs when the waves encounter a surface or other boundary that does not absorb the energy of the radiation and bounces the waves away from the surface. ... This concept is often termed the Law of Reflection.

The reflection of electromagnetic radiation involves the returning or throwing back of the radiation by a surface upon which the radiation is incident. A reflecting surface is generally the boundary between two materials of different electromagnetic properties.
