ultrasound Sound waves with frequencies above 20,000 Hz. Doppler effect An observed change in the frequency of a wave when the source or observer is moving decibel A unit used to compare the loudness of different sounds. longitudinal wave a wave in which the particles of the medium vibrate pa...
changes in percieved frequency when a source of waves and observer of wavesa re moving relative to each other has to do w relative speed to the two objects not limited to sound (also used for light doppler effect: observer/source is moving closer ...
Sound Waves are... LONGITUDINAL For all Wave Motion... It is not the medium that travels, but a pulse that travels. (energy) Speed of Gas Depends on temperature and mass of particles in the gas. Water vapor in the air increases the speed. Intensity of Sound Proportional to the square ...
Two waves arrive at the same location and interfere. The resultant sound wave is smaller than either of the two original waves. What is it called?A. constructive interferenceB. angular interactionC. destructive interferenceD. in-phase waves C A pair of waves are in phase. What occurs when ...

用Quizlet學習並牢記包含The speed of any mechanical wave as it propagates through a medium is dependent mainly on the、The shortest time interval in which a wave motion completely repeats itself (i.e., makes one complete vibration or oscillation) is calle
longitudinal waves Crest occurs at high pressure highest amplitude point Trough occurs at low pressure lowest amplitude point Speed of Sound depends on medium Air at 20°C = 343 m/s Air at 0°C = 331 m/s Elasticity and Inertia strongly influence speed of sound ...
