A disturbance that transfers energy from place to place
A Wave
Waves are created when ________ causes a medium to vibrate.
Energy
A wave the MUST have a medium to travel through
Mechanical Wave
The HIGHEST point of a wave
Crest
The maximum distance of the wave from its rest position; the height of the wave
Amplitude
What a wave travels through
Medium
The ability to do work or create change
Energy
up and down; side-to-side motion
Transverse Waves
The parts of te wave that are far apart
Rarefactions
The distance between two corresponding parts of a wave
crest to crest; trough to trough
compression to compression; rarefaction to rarefaction
Wavelength
_________________ are molecules moving back and forth
Vibrations
Stationary energy; Stored energy
Potential Energy
A wave that does NOT need a medium to travel through
Electromagnetic Waves
The parts of the wave that are CLOSE together
Compressions
The number of waves passing a specific point in a specific time period; measured in hertz
Frequency
3 types of mediums
Gasses; Liquids; Solids
Energy used for movement; active energy
Kinetic Energy
Moves parallel to the medium
back and forth motion
Longitudinal Waves
The LOWEST point of a wave
Trough
Also known as wave speed
Velocity
A longer wavelength = _________ frequency
lower
Higher
A combination of transverse and longitudinal waves
- Occurs at the surface between two mediums
- Results in a circle motion
Surface Waves
The undisturbed position of the particles if they do not vibrate
Rest/Equilibrium Position
Wavelength x frequency =
Velocity
