Wavelength The distance between one point on a wave and the nearest point moving with the same speed and direction (Crest to Crest or Trough to Trough)
Frequency Number of wavelengths that pass by a point each second
Law of Reflection The angle that the incoming wave makes with the normal equals the angle that the outgoing wave makes with the normal
Refraction The change in direction of a wave when it changes speed as it travels form one material to another
Diffraction Bending of waves around an object
Opaque Materials that let no light pass through it
Translucent Only allows some light to pass through it
Transparent Allows nearly all light to pass through it
Reflect When light bounces off an object
Absorb When all light is absorbed into an object
Transmit When light goes through an object
