Wave Basics
A disturbance moves through a medium, yet the particles return to where they started. What is being transferred?
Energy
A wave that requires a medium to travel is called what?
Mechanical
The height of a wave from rest position is called what?
Amplitude
A wave passes 10 times in 5 seconds. What is the frequency?
2 Hz
The force caused by moving charges is called what?
Magnetism
Particles oscillate but do not travel with the wave. What stays in place overall?
Matter
A wave that can travel through space without a medium is what type?
Electromagnetic
The distance between two crests is called what?
Wavelength
A wave takes 0.5 seconds per cycle. What is its frequency?
2 Hz
Opposite poles do what?
Attract
A student claims waves move objects across distances. What concept are they confusing?
Matter
Particles move perpendicular to wave motion. Name the wave type.
Transverse
The number of waves passing per second is known as what?
Frequency
A wave travels 6 meters in 3 seconds. What is its speed?
2 m/s
Like poles do what?
Repel
If particles only vibrate locally, what type of transfer is occurring?
Energy
Particles move parallel to the direction of energy transfer. Name the wave type.
Longitudinal
The time it takes one wave to pass a point is called what?
Period
A wave has wavelength 2 m and frequency 3 Hz. What is speed?
6 m/s
The invisible region where magnetic forces act is called what?
Magnetic field
A wave passes, particles return to equilibrium. What property of waves explains this behavior?
Vibration
A wave contains compressions and rarefactions. What type is it?
Longitudinal
If frequency increases in the same medium, what must decrease?
Wavelength
If speed stays constant and frequency doubles, what happens to wavelength?
Halves
Magnetism in materials comes from aligned what inside atoms?
Electrons
