  • Front
  • Back
A repetitive motion that stays in one location
OSCILLATION
A repetitive motion that moves to a different location
WAVE
For example, the up and down motion causing a ripple in the water
OSCILLATION
For example, the ripples in the water moving outward
WAVE
For example, a pendulum swinging
OSCILLATION
What carries energy and information over great distances?
WAVES
Another word for vibration
OSCILLATION
A wave with the oscillation perpendicular to the wave motion
TRANSVERSE
A wave with the oscillation parallel to the wave motion
LONGITUDINAL
For example, light waves and ocean waves
TRANSVERSE
For example, sound waves
LONGITUDINAL
For example, when we used the spring to make a rippling wave
TRANSVERSE
For example, when we used the slinky to see the coils compress along the length of the slinky
LONGITUDINAL
Measure of how often a wave goes up and down
FREQUENCY
Unit for frequency
HERTZ (Hz)
Equation for frequency (using wavelength and velocity)
FREQUENCY = VELOCITY / WAVELENGTH
The larges amount the wave goes above or below the average
AMPLITUDE
The length of one complete cycle
WAVELENGTH
The distance from crest to crest (or any point on a wave to the repeating point)
WAVELENGTH
Unit for amplitude
DEGREES or METERS
Unit for wavelength
METERS
Equation for velocity
VELOCITY = FREQUENCY x WAVELENGTH
Equation for WAVELENGTH
WAVELENGTH = VELOCITY / FREQUENCY
Symbol for wavelength
LAMBDA (upside down Y)
Symbol for velocity
v
How fast the wave can transmit an oscillation from one place to another
VELOCITY
As frequency increases and velocity remains constant, the wavelength..
DECREASES
As wavelength increases and velocity remains constant, the frequency..
DECREASES
As more energy is put into a vibrating string, the amplitude
INCREASES
Wavelength and frequency have a(n) __ relationship.
INVERSE
Wavelength and speed have a(n) __ relationship.
DIRECT (or PROPORTIONAL)
Speed and frequency have a(n) __ relationship.
INVERSE
