Term | Definition |
---|---|
Diffraction | The bending of a wave around an object |
Refraction | The bending of waves as they pass from one medium to another at an angle |
Standing wave | A pattern of vibration that 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 interference of sound waves that are used to tune piano strings |
Interference | The combination of two or more wave that results in a single wave |
Nodes | Points in a standing wave that have no vibration due to destructive interference |
Sound | Vibrations the air to a person's or animal's ear |
Pitch | The quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone |
Infrasonic | A sound so low a human can't hear it |
Ultrasonic | A sound so high a human can't hear it |
Doppler | A change in frequency due to the Doppler effect |
Acoustics | The science concerned with the production, control, transmission, reception, and effects of sound |
