|---|---|---|---|---|---|
| a disturbance that transfers energy from one place to another without requiring matter to move the entire distance | Waves
🗑
|
||||
| the distance between a crest or trough of a wave and line through the center of a wave | Amplitude
🗑
|
||||
| a substance through which a wave moves | Medium
🗑
|
||||
| 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
🗑
|
||||
| a wave, such as a sound wave or an earthquake wave, that transfers energy through matter | Mechanical wave
🗑
|
||||
| the number of wavelengths (or wave crests) that pass a fixed point in a given amount of time, usually one second | Frequency
🗑
|
||||
| a type of wave in which the disturbance moves at right angles, or perpendicular,to the direction in which the wave travels | Transverse Wave
🗑
|
||||
| the bouncing back of a wave after it strikes a barrier | Reflection
🗑
|
||||
| a type of wave in which the disturbance moves in the same direction that the wave travels | Longitudinal Wave
🗑
|
||||
| the bending of a wave as it crosses the boundary between two mediums at an angle other than 90 degrees | Refraction
🗑
|
||||
| the highest point, or peak, of a wave | Crest
🗑
|
||||
| the spreading out of waves as they pass through an opening or around the edges of an obstacle | Diffraction
🗑
|
||||
| the lowest point, or valley, of a wave | Trough
🗑
|
||||
| the meeting and combining of waves; the adding or subtracting of wave amplitudes that occurs as waves overlap | Interference
🗑
|
||||
| a type of wave that is produced by a vibrating object and that travels through matter | Sound
🗑
|
||||
| the change in perceived pitch that occurs when the source or the receiver of a sound is moving | Doppler Effect
🗑
|
||||
| a rapid, back-and-forth motion | Vibration
🗑
|
||||
| the amount of energy a sound wave has | Intensity
🗑
|
||||
| a space containing no particles of matter | Vacuum
🗑
|
||||
| the unit used to measure the intensity of a sound wave | Decibel
🗑
|
||||
| the quality of highness or lowness of a sound | Pitch
🗑
|
||||
| the strengthening of an electrical signal,often used to increase the intensity of a sound wave | Amplification
🗑
|
||||
| the unit used to measure frequency;one hertz is equal to one complete wavelength per second | Hertz
🗑
|
||||
| the scientific study of sound; the behavior of sound waves inside a space | Acoustics
🗑
|
||||
| sound waves with frequencies above 20,000 hertz, the upper limit of typical hearing levels in humans; use of sound waves with frequencies above 20,000 hertz for medical purposes | Ultrasound
🗑
|
||||
| the sending out of high-pitched soundwaves and the interpretation of the returning echoes | Echolocation
🗑
|
||||
| the strengthening of a sound wave when it combines with an object’s natural vibration | Resonance
🗑
|
||||
| instruments that use echolocation to locate objects underwater; acronym for “sound navigation and ranging“ | Sonar
🗑
