Refraction The bending of waves as they pass from one medium to another at an angle.
Standing Wave a pattern of vibration the resembles a stationary wave
Reflection the bouncing back of a wave when it meets a surface or boundary
Constructive interference Interference that increases amplitude
Destructive interference interference that decreases amplitude
Principle of superposition method of adding crests and troughs of interfering waves together to describe a new wave
Beats sounds produced by the inference of sound waves that are used to tune piano
Interference The interaction between two waves that meet
Nodes On a standing wave where it has mina ble amplitude
Sound sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid.
Pitch A high pitch sound corresponds to a high frequency sound wave and a low pitch
Infrasonic Sources of infrasound in nature include volcanoes, avalanches, earthquakes and meteorites
Ultrasonic The term sonic is applied to ultrasound waves of very high amplitudes.
Doppler Waves emitted by an object traveling toward an observer get compressed
