Waves
What is a mechanical wave
the highest point on a wave
What is the Crest?
the ability to cause changes in matter
What is energy?
Before a sound wave is created, an object must first do this
What is....VIBRATE?
When air molecules move back creating a region of lower density it creates ......
What is......RAREFACTION?
Energy causes matter to move up and down or back and forth at right angles in this type of wave
What is a Transverse Wave
the horizontal distance either between two crests or two troughs of two consecutive waves
What is a wavelength
Has the smallest bones in the body: the hammer, anvil, and stirrup.
What is.....THE INNER EAR?
Sound reflects off of this type of surface
What are....HARD SURFACES?
Sound waves travel fastest through this phase of matter.
What are.......SOLIDS?
Matter in the medium moves forward and backward along same direction that the wave travels
What are compressional waves
the lowest point (valley) of a wave
What is the trough?
A pair of flaps on either side of the larynx that are responsible for the production of sound including speech.
What are....VOCAL CORDS?
The energy of a sound wave can be measured by the....
What is....the Decible Scale?
This property also effects the speed of sound. Based on the number of collisions within a substance.
What is....TEMPERATURE?
Rhythmic disturbances that carry energy without carrying matter
What are Waves
the peak value (greatest value either positive or negative) of a wave
The number of waves that pass a fixed point in a given amount of time; measured in Hertz (Hz)
What is the frequency?
When sound waves moves from a source based on the movement of the sound source or the listener, this is known as the....
What is.....DOPPLER EFFECT
The amplitude of a sound wave refers to the amount of ____________ it has.
What is.......ENERGY?
Do not need matter to transfer energy but they can go through matter
What are Electromagnetic Waves
the part of of the compressional wave where the particles are spread out
What is the rarefaction?
The cochlea can be found in this part of the ear.
What is.....THE INNER EAR?
Bats and dolphins use this to help them navigate:
What is....ECHOLOCATION
The human perception of how much energy a sound wave carries refers to a sound's
What is......LOUDNESS?
