|
Motions that repeat in a regular cycle
|
Periodic motion
|
|
|
the motion that results from the directly proportional forces two and from the equilibrium position
|
simple harmonic motion
|
|
|
Time to complete one cycle of motion
|
Period
|
|
|
The maximum distance that the object moves from the equilibrium
|
amplitude
|
|
|
the force exerted by a spring is directly proportional to the amount that the spring is stretched
|
Hooke's law
|
|
|
a contraption with a bob held by a string
|
pendulum
|
|
|
When small forces are applied at regular intervals to a vibrating or oscillating object and the amplitude of the vibration increases
|
Resonance
|
|
|
a single bump or disturbance that travels through a medium
|
wave pulse
|
|
|
generated when the wave moves up and down at the same rate
|
periodic wave
|
|
|
A wave that vibrates perpendicular to the direction of the wave's motion
|
transverse wave
|
|
|
A wave that releases pulses of closely-spaced turns in different directions
|
Longitudinal wave
|
|
|
A wave with particles that move in a direction that is both parallel and perpendicular to the direction of wave motion
|
Surface wave
|
|
|
A disturbance that carries energy through matter or space
|
Wave
|
|
|
States that the displacement of a medium caused by two or more waves is the algebraic sum of the displacements of the individual waves
|
Principle of Superposition
|
|
|
Results from the superposition of two or more waves; can be constructive (wave displacements in the same direction) and destructive (waves with equal but opposite amplitudes)
|
interference
|
|
|
The stationary point where two equal wave pulses meet and are in the same location, having a displacement of zero
|
Node
|
|
|
The point with the largest displacement when two wave pulses meet
|
Antinode
|
|
|
A Wave that appears to be standing still, produced by the interference of two traveling waves moving in opposite directions
|
Standing Wave
|
|
|
An erect or inverted returning wave that results from some of the energy of the incident's pulse being reflected backward
|
Reflected Wave
|
|
|
The change in direction of waves at the boundary between two different media
|
refraction
|
|
|
The bending of light around the barrier
|
Diffraction
|
