100
A sound wave is an example of this type of wave.
What is a COMPRESSION wave?
100
ALL waves transfer this from place to place.
What is ENERGY?
100
Mechanical waves need this in order to be transmitted.
What is a MEDIUM, or MATTER, or PARTICLES, or a SOLID, LIQUID, or GAS?
100
All sound starts with some sort of a _________.
What is a VIBRATION?
100
This type of wave needs a medium in order to transmit its energy.
What is a MECHANICAL WAVE?
200
Slinky waves and ocean waves are examples of this type of wave.
What is a TRANSVERSE wave?
200
This wave is carrying more energy.
What is the wave on the LEFT?
200
This is why sound cannot travel in the vacuum of outer space.
What is, there are no particles to pass on the wave energy?
200
What controls how high or low pitched a sound is?
What is the sound wave's FREQUENCY?
200
This wave has a higher FREQUENCY.
What is the BOTTOM wave?
300
These arrows show how to measure this important characteristic of a wave.
What is AMPLITUDE?
300
This wave is carrying LESS energy.
What is the wave on the LEFT?
300
If you want to decrease the AMPLITUDE of a wave, you should decrease its ____________, by using something to _____________ it.
What is decrease its ENERGY by using something to ABSORB it?
300
This controls the volume of a sound.
What is the sound wave's AMPLITUDE?
300
This wave has a higher AMPLITUDE.
What is the UPPER wave?
400
These are the three ways to measure a single wave's wavelength.
What is crest to crest, trough to trough, or every other node?
400
Increasing either of these two wave characteristics, will increase the ENERGY of the wave.
What is FREQUENCY or AMPLITUDE?
400
Sound travels fastest through this type of medium.
What is a SOLID medium?
400
One example each of a material that could transmit, reflect, and absorb sound.
What is:
air/water/ground transmit sound
concrete/smooth hard surfaces reflect sound
cotton/felt/soft porous materials absorb sound
400
DAILY DOUBLE
If this wave graph was created in 1 second, this is the frequency of this wave.
500
The number of full waves shown in this diagram.
What is THREE?
500
As wavelength increases, energy ________.
What is DECREASES?
500
This explains why soundproofing lowers the volume of a sound.
What is, soundproofing ABSORBS some of the sound waves' ENERGY, lowering their AMPLITUDE and therefore the volume.
500
These are the main purposes of the outer, middle, and inner ear.
What is the outer ear catches sound waves, the middle ear amplifies sound waves, the inner ear turns sound waves into electric signals to send to the brain?
500
These are the names of the three smallest bones in the human body.
What are the HAMMER (malleus), ANVIL (incus), and STIRRUP (stapes)?
