Longitudinal wave
|
The particle motion and the wave velocity are parallel to each other
EX. stretching a spring |
|
Transverse wave
|
Particle motion is perpendicular to the direction of the wave velocity
EX. shaking a cord up and down or side to side |
|
Wavelength
|
Distance from any point on the wave to the adjacent point with similar oscillation
|
|
Amplitude
|
Max displacement from equilibrium
|
|
Frequency
|
Number of oscilations
|
|
Period
|
Time it takes to travel one wavelength
|
|
Hertz
|
Measure of frequency = 1 cycle per second
|
|
wave speed (v)
|
Wavelength/ Period
|
|
Sound
|
Propagation of longitudinal waves through matter
|
|
Intensity
|
Rate of sound energy. W/m^2
|
|
Decibel (dB0
|
One tenth of a bel (B) Measures intensity
|
|
Doppler effect
|
Reason for cars passing and sound goes away after a gradual build with the approach
|
|
Redshift
|
Light is moving away and appears red due to changes in frequency
|
|
Resonance
|
Max energy transfer to the system
