  1. ENERGY Ability to do work WAVE Disturbance that Transfers energy from place to place

  2. Medium – The material through which a wave travels Mechanical Wave – waves that require a medium through which to travel.

  3. Transverse Waves-waves that move the medium at right angles to the direction in which the waves travel. Longitudinal Wave – move the particles of the medium parallel to the direction that the waves are traveling.

  4. CREST – The Highest part of a wave TROUGH- The lowest part of a wave

  5. Rarefaction- The parts where the coils spread out, or rarefied Compression-The parts where the coils are close together

  6. Vibration – repeated back and forth up and down motion Seismograph-Records the ground movements caused by seismic waves as they move through Earth.

  7. Frequency-A wave is the number of complete waves that pass a given point in a certain amount of time Hertz (Hz) – Units of measurement for frequency

  8. Node-Destructive interference causes two waves to combine to produce an amplitude of zero. Antinode-The crests and troughs of the standing wave.

  9. Primary waves-longitudinal seismic waves Secondary waves-transverse seismic waves

  10. Reflection-When an object or wave hits a surface through which it cannot pass, it bounces back. Angle of Reflection – Is the angle between the reflected waved and the imaginary line.

  11. Seismic Wave – Waves produced by earthquakes Surface Waves-combination of transverse and longitudinal waves.

  12. Destructive Interference-When the amplitude of two waves combine with each other producing a smaller amplitude. Constructive Interference-Whenever two waves combine to make a wave with a larger amplitude.

  13. Diffraction-The bending of waves around the edge of a barrier is known as a diffraction. Angle of Incidents-Between the incoming wave and the imaginary perpendicular line.

  14. Wavelength-The distance between two corresponding parts of a wave. Standing Wave-wave that appears to be standing still.

  15. Tsunami-Earthquakes that occur under water can cause huge surface waves on the ocean floor. Amplitude – The maximum distance the medium carrying the wave moves away from its rest position.

  16. Interference-The effect that occurs when two or more waves meet.
