Can you hear me now?
This is the first step of cellular communication.
What is talking on the phone?
Frequency of a wave multiplied by the wavelength results in this.
What is wave speed?
This is the minimum frequency of ultrasound.
What is 20,000 Hz?
This is the distance one cycle of a wave travels.
What is a wavelength?
These waves can be the size of mountain ranges.
What are radio waves?
This is the second step of cellular communication.
What is "the phone does its thing"?
The wave speed divided by the wavelength is this.
What is frequency?
This is the tool that creates ultrasound.
What is a transducer?
This is how many cycles occur within one second.
What is frequency?
These waves are the smallest that we know.
What are gamma rays?
This is the third step of cellular communication.
What is the cellular tower network?
The wave speed divided by the frequency is this.
What is wavelength?
This is applied to a surface before an ultrasound is performed.
What is a gel?
This can be called a crest or a trough.
What is a peak?
These waves include the light spectrum.
What are visible waves?
This is the fourth step of cellular communication.
What is "the other phone does its thing"?
A wave with a frequency of 2 Hz and a wavelength of 10 meters has this wave speed.
What is 20 meters/second?
This is what creates the ultrasound waves when electricity is applied.
What are piezoelectric crystals?
This is the level at which no wave is occurring.
What is equilibrium?
These waves are the next smallest to gamma rays.
What are x-rays?
This is the fifth step of cellular communication.
What is the other person hears you?
A wave with a speed of 100 meters/second and a wavelength of 25 meters has this frequency.
What is 4 Hz?
This is reason why x-rays can cause cancer while ultrasound does not.
What is ionizing radiation?
This is the distance between a wave's peak and equilibrium.
What is amplitude?
These waves are beyond human sight although some animals can see them.
What is infrared?
