| Question | Answer |
|---|---|
| the change in direction of a wave when it encounter and obstacle or edge | diffreation |
| the bending of wave as they pass one medium to another at an angle | refraction |
| standing wavea pattern of vibration that resembles a stationary standing | standing wave |
| the bouncing back of a wave when it meets a surface or boundary | reflection |
| infterference that increase ampitude | constructive interference |
| interference that decrease ampitude | Destructive interference |
| =method of adding crest and throughs of interfering wave together to describe a new wave | method of adding crest and throughs of interfering wave together to describe a new waveprinciple of superposition |
| sounds produced by the inference of sounds waves that are used to tune piano strings | beats |
| the combination of two or more waves that results in a single | interference |
| points in a standing wave that have no vibration due to destructive interference | nodes |
| a form of energy that transfers through particles of matter as compression waves. | sound |
| describes how high or low a sound is | pitch |
| relating to or denoting sound waves with a frequency below the lower limit of human audibility | infrasonic |
| vibrations of frequencies greater than the upper limit of the audible range for human | vibrations of frequencies greater than the upper limit of the audible range for ultrasonic |
| Doppler effect in physics is defined as the increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move towards (or away from) each other. | doppler effect |
| a branch of continuum mechanics that deals with the study of mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound | acoustic |
