Waves

PULSE : one wave cycle, single vibration or movement
AMPLITUDE : maximum disturbance of a particle from its rest (equilibrium) position
TRANSVERSE PULSE : particles of medium move at right angles with to the direction of the propagation of the pulse
SUPERPOSITION : the addition of the disturbances of the two pulses at the same time
CONSTRUCTIVE INTERFERENCE : occurs when the resulting disturbance is larger than the individual disturbances which created it
DESTRUCTIVE INTERFERENCE : when resultant displacement is smaller than the individual displacement
TRANSVERSE WAVE : succession of transverse pulses
WAVELENGTH : distance between 2 consecutive, corresponding points on the wave
CREST : maximum posistive amplitude
TROUGH : maximum negative amplitude
FREQUENCY : number of times the wave cycle is repeated (Hz)
PERIOD : time it takes a wave to complete 1 wave cycle
IN PHASE : waves that are - moving same direction, same wavelength, crest and trough occur at same time
OUT OF PHASE : waves not in phase
f=1/T
WAVE SPEED : v=fA
