Waves Waves Waves
What is longitudinal, transverse, and surface waves?
What is wavelength, period and frequency, amplitude, rest position, crest, and trough.
The part of the outer ear that is visible.
What is the pinna?
This wave cannot travel in a vacuum.
What is a sound wave?
A mechanical wave must have this in order to travel.
What is a medium?
What is the higher the frequency, the higher the energy.
The location of the eustachian tube.
What is the middle ear?
Sound waves do this when travelling from a solid to air.
What is slow down?
This type of wave has a perpendicular disturbance.
What is a transverse wave?
This increases as the number of troughs passing a point in a given time increases.
What is frequency?
Found within the inner ear and acts as the "microphone" of the ear.
What is the cochlea?
Sirens have a higher pitch as it approaches due to this.
What is closer spacing of wave crests?
This describes the disturbance in a longitudinal wave.
What is a parallel wave disturbance.
This decreases as the number of crests passing a point in a given time increases.
What is wavelength?
The organ of Corti (found within the inner ear) contains hairs that do this.
What is receive vibrations and transmit them into electrical impulses that are sent to the brain?
What is increased space between crests?
This is the cause of the circular wave motion seen in surface waves.
What is a combination of longitudinal and transverse waves?
The type of frequency exhibited by a wave with short wavelengths and crests that are close together.
What is high frequency?
The range of frequencies audible to humans.
What is 20 Hz to 20,000 Hz?
The Doppler effect is used to do these things in baseball and in hospitals.
What is measure speed and monitor blood flow?
