TermDefinition
wave rhythmic disturbance that carries energy through matter or space
amplitude determines loudness of a sound wave
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
convex mirror used to show a large area on a smaller mirror (security), image is smaller and upright
concave mirror image formed is upside down unless object is at or in front of the focal point
convex lens divergent lens, helps people who have farsightedness (trouble reading)
concave lens convergent lens, helps people who have nearsightedness (trouble seeing objects that are far away)
