TermDefinition
Wave A disturbance that transfers energy from place to place.
Energy The ability to do work.
Amplitude The maximum distance the particles of a medium move away from their rest positions as a wave passes through the medium.
Wavelength Distance between 2 corresponding points (crest to crest, trough to trough).
Frequency The number of complete waves that pass a given point in a certain amount of time.
Vibration Repeated back
Crest The highest part of a transverse wave.
Trough The lowest part of a transverse wave.
Resting Position On a graph it would be located at 0.
Mechanical Waves Travel through gases, liquids or solids.
Medium Material through which a wave travels.
Damping Any type of friction that causes a wave to decrease in frequency and amplitude.
Speed How far a wave travels in a given amount of time.
Electromagnetic Waves Waves that transfer electric and magnetic energy through the vacuum of space.
Electromagnetic Spectrum The complete range of electromagnetic waves placed in order of increasing frequency.
Visible Light Electromagnetic waves that are visible to the human eye.
Opaque A material that reflects and absorbs all of the light that strikes it.
Primary Colors Three colors that can be used to make any other color. (Red, yellow, and blue.)

Law of Reflection The rule that the angle of reflection equals the angle of incidence.
Plane Mirror A flat mirror that produces an upright, virtual image the same size as the object.
Concave Mirrors A mirror with a surface that curves inward.
Convex Mirrors A mirror with a surface that curves outward.
Refraction The bending of waves as t
