waves
| Question | Answer |
|---|---|
| waves | traveling disturbence that carries energy from one place to another |
| Vibration | movement that follows the same path over and over |
| Medium | material through which a mechanical wave travels |
| Mechanical wave | wave that disturbs a medium |
| Electromagnetic wave | wave that consists of electric and magnetic fields |
| crest | high point of a wave |
| Trough | low point of a wave |
| Amplitude | greatest distance resting position of a wave |
| Wavelength | distance between the similar points on a wave |
| Frequency | Number of waves that pass a point in a certain amount of time |
| Transverse waves | wave in which the medium is at a right angle |
| Longitudinal wave | wave in which the medium is parrell too the wave |
| Surface wave | wave that is both and transverse and parallel wave |
| compression | squeezing together |
| Reflection | bouncing back of waves upon reaching another surface |
| Refraction | bending of waves due to the change in speed |
| Diffraction | bending of waves around something |
| Interference | Interaction of 2 or more waves when they crash into each other |
| standing wave | wave that does not appear to be moving |
| Resonant frequency | Frequency at which a standing wave occurs |
| pitch | property of sound that depends on frequency |
| ultrasonic | sound above the range of human hearing |
| infrasonic | sound below the range of human hearing |
| Doppler effect | change in sound or light that occurs between the source and the observer |
| intensity of sound | amount of energy carried by a wave |
| acoustics | science of sound |
| sound quality | blending of pitches to produce sound timbre |
| timbre | blending of pitches to produce sound, sound quality |
| fundamental tone | note produced at the lowest frequency at which a standing wave occurs |
| over tone | tone produced at frequencies higher then the fundamental |
| sonar | technique of using sound waves to measure distance |
