Term | Definition |
wave | rhythmic disturbance that carries energy through matter or space |
amplitude | determines loudness of a sound wave (compression width) or intensity of a light wave (crest height) |
pitch | describes highness or lowness of a sound |
resonance | the increase in amplitude that occurs when outside vibrations match an object's natural frequency (breaking glass with sound) |
frequency | the number of waves that pass a point in one second, measured in Hertz (Hz) |
compression | area on a sound wave where molecules are "squished" together during a vibration |
Doppler Effect | a change in frequency (pitch) observed when the source of a sound and an observer are in motion relative to each other |
refraction | bending of waves that occurs upon entering a new medium and changing speed |
rarefaction | part of a sound wave where molecules are "rarely" found during a vibration |
diffraction | the bending of waves around a barrier |
constructive interference | waves combine to form a wave with a larger amplitude |
destructive interference | waves combine to form a wave with a smaller amplitude (used in noise cancellation technology) |
gamma rays | electromagnetic waves with the smallest wavelength and highest frequency |
radio waves | electromagnetic waves with the longest wavelength and lowest frequency |
