Mr Spade Waves

Characteristics of Waves

QuestionAnswer
Wave A disturbance that transfers energy from place to place.
Medium Material through which a wave travels
Transverse Waves that move the medium at right angles to the direction of the wave
Longitudinal Waves that move the medium parallel to the direction of the wave
Crest The highest part of a transverse wave
Trough The lowest part of a transverse wave
Compression The part of a longitudinal wave where the particles of closer together
Rarefaction The part of a longitudinal wave where the particles are farther apart.
Amplitude The maximum distance that the particles of the medium move from their rest position
Wavelength The distance between two corresponding parts of a wave
Frequency The number of complete waves that pass by a given point in a certain amount of time
Hertz Unit for frequency
Sound A disturbance that travels through a medium as a longitudinal wave
Loudness Your perception of the energy of a sound. It depends upon the amplitude of a sound wave and the distance from the source.
Pitch A description of how high or low a sound seems to a person. It depends upon the frequency of a sound.
Mechanical Waves that require a medium through which to travel
Visible Light Electromagnetic waves that humans can see
White Light A mixture of all the colors of visible light
Transparent Material that transmits most of the light that strikes it
Translucent Material that scatters light as it passes through
Opaque Material that reflects or absorbs all of the light that strikes it
Convex A lens that is thicker at the center and thinner at the edges
Concave A lens that is thicker at the edges and thinner at the center
Reflection When a wave hits a surface and it bounces back
Refraction When a wave enters a new medium at an angle, causing the wave to bend
