What is a Wave?
A disturbance that moves energy through space or matter is called what?
Wave
A wave that needs a medium to travel is called what?
Mechanical
The highest point of a wave.
Crest
This is the material that a wave travels through.
Medium
This is the force that can pull certain metals.
Magnetism
Waves transfer this, not matter.
Energy
A wave that can travel through space without a medium is called what?
Electromagnetic
The lowest point of a wave.
Trough
Sound travels through air. What does this tell you about sound waves?
Mechanical
The ends of a magnet are called what?
Poles
After a wave passes, particles return to their original position. What does NOT move with the wave?
Matter
Particles move side to side while the wave moves forward. What type of wave is this?
Transverse
The height of a wave from rest position.
Amplitude
Light can travel through space. What does this tell you about light waves?
Electromagnetic
Opposite poles do what?
Attract
Particles move back and forth but stay in the same place. What is this motion called?
Vibration
Particles move back and forth in the same direction as the wave. What type is this?
Longitudinal
The distance from crest to crest.
Wavelength
If a wave has more energy, what property is larger?
Amplitude
Like poles do what?
Repel
A wave moves through air, but the air doesn’t travel across the room. What is being transferred?
Energy
This type of wave has compressions and rarefactions.
Longitudinal
In a longitudinal wave, areas where particles are close together are called what?
Compression
If particles are spread far apart in a longitudinal wave, this region is called what?
Rarefaction
The invisible area around a magnet where it exerts force is called what?
Field
