What is crest?
is the lowest point of a transverse wave
is the midpoint point of a transverse wave
is the highest point of a transverse wave
Mechanical waves are created when a source of energy causes a medium to _________________.
vibrate
compress
move
What property of the wave is represented by the letter "B"?
amplitude
crest
wavelength
What do seismic waves and sound waves have in common?
They're mechanical waves
They're permanent waves
They're phonetic waves
A wave with a short wavelength will have a...
low frequency
high frequency
What is amplitude?
the distance from the midpoint of a wave and the wave.
the distance between the midpoint of a wave and the crest.
the difference between the frequency of a wave and the time.
What is a wave?
a disturbance that transfers energy
any type of energy that makes particles move
any type of matter that vibrates back and forth
What does it mean when a wave's amplitude increases?
It's moving through a denser medium.
It's carrying more energy.
Its frequency also increases.
What are the two kinds of waves?
mechanical and electronic
long and short
mechanical and electromagnetic

It continues moving
It returns to its original resting position
Frequency is...
the number of waves that pass a given point in one hour
