Visible Light- The Light we see

                    The light we see is all colors combined.  When we slow up light by refracting it through a Prism, we see the rainbow.   The rainbow is a way for us to see how color is brought up.   It is always in this order….

                   Red, Orange, Yellow, Green, Blue, Indigo, Violet

 You can remember these colors in order by remembering the name….

ROY  G.  BIV     

Properties of Waves include - Reflection or the bouncing of waves, continued reflection or echo is reverberation, Refraction or the bending of waves because they slow up or speed up as they pass through a different medium and diffraction or the changing of a wave as it moves around something.
