transverse waves Flashcards
what is a pulse
a single vibration in a given medium
what I an transverse pulse
a single vibration in which the particles are displaced perpendicular to the direction of. a wave propagation/pulse
what is a transverse wave
a wave in which the particles are displaced perpendicular to the direction of wave propagation
what does a transverse wave consist of
crests ( region of displacement above rest position )
troughs 9 region of displacement below rest position )
what si wave lengths
the distance between two successive points which are in phase
the length of one complete cycle of a wave
what is points in phase
points which occupy the same position and move in the same direction
what is points out of phase
points which do not occupy the same position and do not move in the same direction
what is the special name of wave lengths
lambda
what is wave lengths measured in
in “m”
cm= x10 –2
mm= x10 –3
um= x10 –6
nm= x10 –9
pm= x10 –12
what is amplitude (a)
maximum displacement of a wave particles from rest position in m
what is period (T)
it is the time taken to make a complete wave cycle or oscillation.
measure in seconds
what is frequency (f)
the number of complete oscillations or wave cycles which pass a given point in one second.
measured in Hertz (Hz)
what is the formula for frequency and period
f= 1/T
T= 1/f
what is wave speed (v)
the rate of change of distance of a wave
what is the formula for speed
v= distance / time
v= (f)(wave length )
