|
wavelength
|
distance between 2 corresponding parts of a wave
(speed divided by frequency) |
|
|
amplitude
|
*distance from rest position
*one-half the width of the wave at the widest point |
|
|
speed of a wave
(formula) |
wavelength X frequency
|
|
|
period
|
time for 1 cycle to occur
|
|
|
Hertz (Hz)
|
*unit of measurement for frequency
(1 cycle per second) |
|
|
frequency
|
# of cycles that occur in 1 second
*speed divided by wavelength |
|
|
reflection
|
the wave can bounce off obstacle and go in a new direction
|
|
|
refraction
|
the wave can pass straight into and through the onstacle
|
|
|
diffraction
|
the wave can bend around or through holes in the obstacle
|
|
|
resonance
|
when you vibrate an object at its natural frequency and get large amplitude waves
|
|
|
harmonics
|
# of "bumps" on a wave

|
|
nodes
|
points on a wave where there is not motion
|
|
|
antinodes
|
place on a wave where the amplitude is largest
|
|
|
fundamental
