1.1 wave Waves transfer energy.
medium mechanical wave A disturbance that transfers energy from one place to another without requiring matter to move the entire distance. transverse wave longitudinal wave CHAPTER RESOURCES KEY CONCEPT SUMMARY

1.1 medium Waves transfer energy.
mechanical wave A substance through which a wave moves. transverse wave longitudinal wave CHAPTER RESOURCES KEY CONCEPT SUMMARY

1.1 mechanical wave Waves transfer energy.
medium mechanical wave A wave, such as a sound wave or a seismic wave, that transfers kinetic energy through matter. transverse wave longitudinal wave CHAPTER RESOURCES KEY CONCEPT SUMMARY

1.1 transverse wave Waves transfer energy.
medium mechanical wave A type of wave in which the disturbance moves at right angles, or perpendicular, to the direction in which the wave travels. transverse wave longitudinal wave CHAPTER RESOURCES KEY CONCEPT SUMMARY

1.1 longitudinal wave Waves transfer energy.
medium mechanical wave A type of wave in which the disturbance moves in the same direction that the wave travels. transverse wave longitudinal wave CHAPTER RESOURCES KEY CONCEPT SUMMARY

Waves have measurable properties.
1.2 Waves have measurable properties. water level at rest fixed point crest trough crest Wavelength is the distance from one crest or trough to the next. trough amplitude wavelength frequency Amplitude is the distance a medium moves above or below its position at rest. Frequency is the number of wavelengths passing a fixed point in a certain amount of time. CHAPTER RESOURCES SECTION OUTLINE

Waves have measurable properties.
1.2 Waves have measurable properties. crest trough VISUALIZATION Watch the graph of a wave form. amplitude wavelength frequency CHAPTER RESOURCES SECTION OUTLINE

1.2 crest Waves have measurable properties.
trough amplitude The highest point, or peak, of a wave. wavelength frequency CHAPTER RESOURCES KEY CONCEPT SUMMARY

1.2 trough Waves have measurable properties.
crest trough trough amplitude The lowest point, or valley, of a wave. wavelength frequency CHAPTER RESOURCES KEY CONCEPT SUMMARY

1.2 amplitude Waves have measurable properties.
crest amplitude trough amplitude The maximum distance that a disturbance causes a medium to move from its rest position; the distance between a crest or trough of a wave and line through the center of a wave. wavelength frequency CHAPTER RESOURCES KEY CONCEPT SUMMARY

1.2 wavelength Waves have measurable properties.
crest wavelength trough amplitude The distance from one wave crest to the next crest, or from any part of one wave to the identical part on the next wave. wavelength frequency CHAPTER RESOURCES KEY CONCEPT SUMMARY

1.2 frequency Waves have measurable properties.
crest frequency trough amplitude The number of wavelengths (or wave crests) that pass a fixed point in a given amount of time, usually one second. wavelength frequency CHAPTER RESOURCES KEY CONCEPT SUMMARY

1.3 reflection Waves behave in predictable ways.
refraction The bouncing back of a wave after it strikes a barrier. diffraction interference CHAPTER RESOURCES KEY CONCEPT SUMMARY

1.3 refraction Waves behave in predictable ways.
reflection refraction refraction The bending of a wave as it crosses the boundary between two mediums at an angle other than 90 degrees. diffraction interference CHAPTER RESOURCES KEY CONCEPT SUMMARY

1.3 diffraction Waves behave in predictable ways.
reflection diffraction refraction The spreading out of waves as they pass through an opening or around the edges of an obstacle. diffraction interference CHAPTER RESOURCES KEY CONCEPT SUMMARY

1.3 interference Waves behave in predictable ways.
reflection interference refraction The meeting and combining of waves; the adding or subtracting of wave amplitudes that occurs as waves overlap. diffraction interference CHAPTER RESOURCES KEY CONCEPT SUMMARY
