Electromagnetic Spectrum
(The electromagnetic spectrum shows the relationship between frequncy and wavelentgh of the most common types of waves.)
Some key terms:
Reflection: bouncing back of a wave when it meets a surface or boundary
Diffraction: change in a direction of a wave -bending of a wave as it passes edges
Refraction: Bending of waves as they pass from one medium to another
