    of waves...

    see the glossary here http://www.bbc.co.uk/education/guides/zdwnb9q/revision

    reflection: There is a reflection when waves bounce off a surface.

    refraction: Process by which a wave changes in speed and sometimes direction upon entering a denser or less dense medium. For example, a light ray changes direction when refracted by a lens.

    diffraction: The spreading out of waves when they pass through a gap or around an obstacle.

    reflection also has a slightly different meaning in maths where you might transform a graph into it's mirror image.

    It's not just for graphs. Reflections are defined on geometric spaces.
