what is a wave

disturbance(vibration) that travels through a medium (substance).
When a wave isn't traveling what state is it in.

equilibrium
Once a particle moves at the front, the energy of that particle will
__________ throughout the slinky to the other end. That creates a
__--

travel, wave
Wave transfer ____________ and not __________

transfer waves and not particles
Describe transverse waves
- particles move up and down to the direction of energy transfer
- particles move up and down but energy is transferred left to right
Describe longitudinal wave
- particles move parallel to the direction of energy transfer
- particles move left to right, energy transferred particles move left and right, energy transferred left to right
What can electromagnetic waves do and a example
- can transfer through energy in a vacuum
- Ex: Light waves
what can mechanical waves do and why
- cannot transfer energy in a vacuum
- Ex: sound waves
Parts of transverse waves
- crest(high point)
- trough(low point)
parts of longitudinal wave
- compression(high pressure)
- rarefaction (low pressure)
define wavelength

length of one cycle
units for wavelength

same as for distance. Meters- usually with a prefix like nano
define amplitude

displacement of particles from equilibrium position.
Units of amplitude

same as distance
relationship between amplitude and soun

increased amplitude means louder/more intense sound
define frequency

amount of water cycles that pass in a certain amount og time
units for frequency

hertz, Hz (cycles per second)
relationship between frequency and pitch

increased frequency means higher pitch
define period

the amount of time it takes for one complete cycle (wavelength)
