-
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)
