Crest The highest point of a wave.
Trough The lowest point of a wave.
Frequency The number of waves produce in a set amount of time.
Medium A material through which the energy of the wave moves from one place to another.
Waves A disturbance that transfers energy from one place to another.
Electromagnetic Waves Are made up of changing electric and magnetic fields or Electromagnetic waves (EM waves) are waves that are created as a result of vibrations between an electric field and a magnetic field.
Amplitude A measure of how far a particle in the medium moves away from its normal rest position, half of the difference between the crest and the trough.
Transmission The passing of light wave through matter.
Transparent A material that allows light to transmit through it.
Translucent Materials that transmit light, but the light is scattered into many directions. An object may appear distorted or fuzzy.
Opaque Materials that do not let any light pass through them, they reflect light, absorb the light, or both.
Absorption The transfer of light energy to matter.
Reflection The bouncing of light off of a surface.
Refraction Bending or change in direction of a light wave as it passes from one medium to another.
Wavelength The distance from any point on a wave to an identical point on the next wave pulse.
