Reflections

These can occur in acoustics, seismic waves, surface waves and electromagnetic waves. A mirror is the best example of the reflection of light. [[image:Mirror.jpeg]]
A wave is reflected whenever is reaches a boundary in the medium through which it is traveling. Reflection may be total or partial and may or may not cause the wave to invert depending upon the type of boundary. The portion of the wave that does not cross the boundary is the reflected wave. The portion of the wave that does cross the boundary is the transmitted wave.
