100
Four characteristics that describe a wave
What are speed, wavelength, frequency and amplitude?
100
An indication of how high or low a sound is, which is primarily determined by the frequency of the sound wave
What is pitch?
200
The lowest points of a wave
What are troughs?
200
A wave with a direction of propagation that is perpendicular to its direction of oscillation
What is a Transverse Wave?
200
Also called the ¨eardrum¨ sound waves cause this to vibrate
What is the tympanic membrane?
200
Distance traveled divided by time traveled
What is speed?
200
Sound waves with low pitch have this
What is low frequency?
300
The distance between the crests or the distance between the troughs
What is wavelength?
300
A wave with a direction of propagation that is parallel to its direction of oscillation
What is a Longitudinal Wave?
300
Tiny bones in the ear which transfer oscillations to the cochlea
What are ossicles
300
Any speed that is faster than the speed of sound in that medium
What is Supersonic Speed?
300
Sound waves with high pitch have this
What is high frequency?
400
The height of the wave
What is amplitude?
400
similar to the crests of a transverse wave as demonstrated by compressed sections of a slinky
What are compressions?
400
the cochlea converts these into electrical signals that are sent to the brain and interpreted as sound
What are oscillations?
400
the speed of sound
What is Mach?
400
Waves with frequencies higher than 20,000 Hz
What are Ultrasonic waves?
500
Indicates how many waves hit a certain point every second
What is frequency?
500
Similar to the troughs of a transverse wave as demonstrated by sections of a slinky that are pulled apart
What are rarefactions+
500
Sound is this type of wave
What is longitudinal?
500
This interesting phenomenon is generated when an object travels through the air faster than the speed of sound in air
