Create
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)
