waves and light

TermDefinition
Wave A disturbance that transfers energy from place to place.
Energy The ability to do work or cause change.
Amplitude The maximum distance particles of a medium move away from their rest positions as a wave passes through the medium.
Wavelength The distance between two corresponding parts of a wave.
Frequency The number of complete waves that pass a given point in a certain amount of time.
Vibration A repeated back and forth or up and down motion.
Crest The highest part of a transverse wave.
Trough The lowest part of a transverse wave.
Mechanical Waves The number of times a machine increases a force exerted on it.
Medium The material through which a wave travels.
Electromagnetic wave 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 or absorbs all of the light that strikes it.
Primary Colors Three colors that can be used to make any other color.
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 mirror A mirror with a surface that curves inward.
Convex mirror A mirror with a surface that curves outward.
Refraction The bending of waves as they enter a new medium at an angle.
Lens A curved piece of glass or other transparent material that is used to refract light.
Convex lens A lens that is thicker in the center than at the edges.
Concave lens A lens that is thinner in the center than at the edges.
Resting position a wave is the position in which the wave would sit if there was no disturbance moving through it
Damping a decrease in the amplitude of an oscillation as a result of energy being drained from the system
Speed the rate at which someone or something is able to move or operate.
Primary colors of light Green, Red, and Blue
