Waves Flashcards
medium
the substance or material in which a pulse will move
pulse
is a single disturbance that moves though a medium
transverse pulse
a pulse where all particles that are disturbed move perpendicular to the direction the pulse is moving
amplitude
the maximum disturbance or distance the medium is displaced from its rest position
pulse speed
the distance a pulse travels per unit of time
(v) & v=d/t
principle of superposition
states when two disturbances occupy the same space at the same time the resulting disturbance is the sum of the two
constructive interference
two pulsing meet resulting in a bigger pulse
wave
periodic, continuous disturbances that consist of a train of pulses
wavelength
distance between any two consecutive points in phase (lambda)
period
time taken to complete one wave (t) (s)
frequency
number of waves that pass a point in 1 second (f) (hz)
wave speed
distance a wave travels per unit of time
wave equation
v=f.l (lambda)
longitudinal wave
wave where particles move parallel to the direction of propagation.
compression
region in a longitudinal wave where particles are close
