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
*multiples of the fundamental of a standing wave
nodes
points on a wave where there is not motion
antinodes
place on a wave where the amplitude is largest
fundamental
natural frequency
