Energy vs Matter
A wave passes, particles return to their starting point. What actually traveled forward?
Energy
A wave cannot travel in space because it requires particle interaction. What type is it?
Mechanical
More waves per second describes which property?
Frequency
A wave repeats 20 times in 4 seconds. What is its frequency?
5 Hz
The force created by moving charges is called what?
Magnetism
A student thinks waves push objects across long distances. What are they incorrectly saying waves move?
Matter
A wave moves through a vacuum and is produced by charged particles. What type is it?
Electromagnetic
Time for one complete oscillation describes what?
Period
A wave takes 0.2 seconds per cycle. What is the frequency?
5 Hz
Two magnets repel. What must be true about their poles?
Same poles
Particles oscillate but do not change location overall. What type of motion is this?
Vibration
Particle motion is perpendicular to wave direction. Identify the wave type.
Transverse
If frequency increases in the same medium, what must decrease?
Wavelength
A wave travels 10 meters in 2 seconds. What is its speed?
5 m/s
The invisible region where magnetic force exists is called what?
Field
A student says waves carry objects long distances. What are they confusing waves with?
Matter
Energy travels through regions of compression and rarefaction. Identify the wave type.
Longitudinal
Which property directly reflects energy carried by a wave?
Amplitude
A wave has wavelength 2 m and frequency 4 Hz. What is speed?
8 m/s
Magnetism in materials results from alignment of what inside atoms?
Electrons
Energy moves through particles without permanent displacement. What principle does this describe?
Oscillation
If particle motion aligns with energy transfer direction, what must the wave NOT be?
Transverse
If wavelength increases while speed stays constant, what must happen to frequency?
Decrease
A wave moves at 12 m/s and has frequency 3 Hz. What is wavelength?
4 m
If electron motion cancels out in a material, what property will it lack?
Magnetism
