|
Frequency
|
The number of waves passing a point per second. Unit: Hertz. (sec^-1)
|
|
|
Wavelength
|
The length of a wave (measured from crest to crest or trough to trough). Units: meters.
|
|
|
Velocity of a wave
|
How fast the disturbance travels throught the medium.Units: meters/second.
|
|
|
Period
|
The amount of time for one complete cycle of a wave or periodic motion. Units: seconds
|
|
|
Frequency of a spring SHO
|
|
|
|
Frequency of a simple pendulum
|
|
|
|
velocity of a wave equation
|
|
|
|
transverse wave
|
The particles in the medium move perpendicular to the direction of the wave's motion.
|
|
|
longitudinal wave
|
The particles of the medium move parallel to the direction of the wave's motion.
|
|
|
Amplitude
|
The maximum displacement from equilibrium.
|
|
|
resonant frequency
|
the frequency that a particle or system naturaly vibrates at
|
|
|
Fixed end reflection
|
|
|
|
free end reflection
|
|
|
|
destructive interference
|
two overlaping waves that add to zero
|
|
|
Constructive Interference
|
Two pulses overlap to produce a resultant displacement that is greater than the displacement of either seperate
|
|
|
standing wave
|
a wave the appears to stand still. It is formed when a wave interferes with another wave traveling in the opposite direction.
|
|
|
refraction
|
the change of wavelength and speed as a wave changes medium
|
|
|
relationship b/t tension and velocity
|
as the tension in a string increases, the speed of the wave increases as well.
|
|
|
beats
|
The modulation of a wave when waves close in frequency overlap.
|
|
|
Doppler Effect
|
The apparent change in frequency of a wave when the source and the observer are moving relative to each other.
|
|
|
shock wave
|
when the waves of a hypersonic object overlap to create a great pressure wave
|
