Analog and Digital
Changing a wave
Glass bottle Experiment
True or False
The Ear
100
This type of technology is a representation of something or someone.
What is analog technology?
100
If you increase the amplitude of a wave you also increase this.
What is energy or for sound waves the intensity/volume?
100
When blowing across the top of a glass bottle with more water creates this type of pitch.
What is high pitch?
100
Sound waves are not compression waves.
What is false?
100
There are this many sections of the ear.
What is three?
200
This type of technology converts information into numbers, electronically.
What is digital technology?
200
If you decrease the frequency you also decrease this.
What is pitch?
200
When tapping on a glass bottle with more water their is this type of pitch.
What is low pitch?
200
Light can travel through a vacuum.
What is true?
200
This part of the ear is responsible for your balance.
What is the inner ear?
300
This type of technology takes up little space, but is not in the physical world.
What is digital technology?
300
Show two waves with different amplitudes.
One high amplitude and another low amplitude.
300
By tapping a glass bottle with water, it creates its pitch for this reason.
The water dampens the vibration created by tapping the glass bottle. Without water, then the sound is not dampened.
300
Sound travels 13 times faster through solids than gases.
What is true?
300
This part of the ear makes sounds into vibrations.
What is the middle ear?
400
True/False: Analog sound waves are not continuous and not smooth.
What is false?
400
What is 1.crest 2.wavelength 3.amplitude 4.trough
400
When tapping the glass bottle, your are vibrating what medium.
What is the glass?
400
Solids have molecules closer than liquids, that why sounds can collide quicker through solid particles than liquids.
What is true?
400
This part of the ear turns sound into electrical signals for the brain.
What is the cochlea?
500
Is this clock analog or digital technology.What is analog?
500
When you increase the energy in a pulse wave you increase this.
What is frequency?
500
When blowing across the top of the glass bottle your are vibrating this medium.
What is air?
500
Longitudinal waves travel parallel to the energy transfer and the motion of the wave.
What is true?
500
The function of this part of the ear is to funnel sound into the ear.
What is the outer ear?
