A boy has a cork on his fishing line in a lake. His brother throws a rock in the lake near where he is fishing, and the waves created from the rock splashing cause the boy's cork to bob up and down for over a minute. What is the medium for the waves in this scenario?
the cork
the water
the rock
the fishing line
The distance between two corresponding parts of a wave is its
amplitude
frequency
wavelength
velocity
Longitudinal waves have:
crests and troughs
crests and compressions
compressions and rarefactions
troughs and rarefactions
Longitudinal waves move:
at a right angle compared to the direction the wave is traveling
in a circle compared to the direction the wave is traveling
matter
in the same direction as the wave is traveling
How are sound waves like ripples in a pond?
They are both types of electromagnetic radiation.
They travel faster in water than they do in the air.
They radiate outward from a central point.
They have the same wavelengths.
Sound is measured in

An advantage a digital wave has over an analog wave is
It can be perfectly duplicated.
It is cheaper to make.
It is longer and conserves energy.
It doesn't cause cancer.
What is the main difference between analog and digital technology?
Digital technology reproduces sound more faithfully than analog technology
Analog technology stores information as sound waves; digital technology stores it as strings of ones and zeroes
Analog technology can be used to record sound and images; digital technology can only be used to record sound
Analog technology is based on binary code; digital technology is based on electromagnets
An example of a digital wave looks like
