Term
 Oscillatory Motion
Definition
 the movement of an object back and forth between two opposing points
Term
 Periodic Motion
Definition
 motions which all repeat in a regular cycle
Term
 Period (T)
Definition
 the time needed for an object to repeat one complete cycle of motion
Term
 Amplitude
Definition
 the maximum distance the object moves from the equilibrium position
Term
 Simple Harmonic Motion (SHM)
Definition
 any system in which the force acting to restore an object to its equilibrium position
Term
 Hooke's Law
Definition
 F = -kxStates the force acting on a spring is directly proportional to the amount the spring is stretched
Term
 Simple Pendulum
Definition
 a device that can demonstrate simple harmonic motion when its bob, suspended by a string or light rod, is pulled to one side and released, causing it to swing back and forth.
Term
 Resonance
Definition
 a special form of periodic motion that occurs when small forces are applied at regular intervals to an oscillating/vibrating object and the amplitude of the vibration increases.
Term
 Wave
Definition
 a disturbance that carries energy through matter or space; transfers energy without transferring matter
Term
 Wave Pulse
Definition
 a single disturbance or bump that travels through a medium
Term
 Transverse Wave
Definition
 a wave that vibrates perpendicular to the direction of the wave's travel
Term
 Periodic Wave
Definition
 a wave whose disturbances occur at a constant rate
Term
 Longitudinal Wave
Definition
 A mechanical wave in which the disturbance is parallel to the direction of the wave travel
Term
 Surface Wave
Definition
 a disturbance in which the medium's particles follow a circular path that is at times parallel to the direction of wave travel.
Term
 Trough
Definition
 the low point of a wave
Term
 Crest
Definition
 the high point of a wave
Term
 Wavelength
Definition
 the shortest distance between points on a wave where the wave pattern repeats itself
Term
 Frequency
Definition
 the number of complete oscillations a point on a wave make each second
Term
 Incident Wave
Definition
 a wave pulse that strikes a boundary between two mediums
Term
 Reflected Wave
Definition
 a returning wave that results from some of the energy of the incident waves' pulse being reflected backward
Term
 Principle of Superposition
Definition
 the placement of a medium caused by 2 or more waves is the algebraic sum of the displacements of the individual waves
Term
 Interference
Definition
 results from the superposition of two or more waves; can be constructive or destructive
Term
 Node
Definition
 the stationary point where two equal wave pulses meet and are in the same location
Term
 Antinode
Definition
 the point with the largest displacement when two wave pulses meet
Term
 Standing Wave
Definition
 a wave that appears to be standing still; caused by the interference of two traveling waves in different directions
Term
 Wavefront
Definition
 a line representing the crest of a wave in two dimensions that can show the wavelength
Term
 Ray
Definition
 a line drawn at a right angle to a wavefront; represents the direction of wave travel
Term
 Normal
Definition
 the line in a ray diagram that shows the orientation of the barrier/mirror and is drawn at right angle
Term
 Law of Reflection
Definition
 the angle of incidence is equal to the angle of reflection
Term
 Refraction
Definition
 the change in direction of waves at the boundary between two different mediums
Term
 Diffraction
Definition
 the bending of light around a barrier
