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
