interpreting wave graphs Flashcards
a wave changes…
over time
what can waves travel through
space
what are the 2 different types of wave graphs called
-displacement time graph
-displacement distance graph
what does displacement time graph focus your attention on
oscillations in one point in space
what is an oscillation
a repetitive motion (vibration)
what does a complete oscillation cycle mean
travelling from one side to the opposite side and back to the original position
what is period (t)
time for one complete cycle
what is the amplitude
maximum displacement
where is amplitude always measured from
from he central equilibrium point
what does a displacement distance graph show you the wave shape of
the whole space at that instant
what is wavelength
the distance between 2 consecutive points where oscillation are in phase with eachother
what is distance measured in
metres
when oscillations are out of phase what takes time for the wave energy to do
travel
when oscillation are out of phase when travelling one wavelength takes 1 cycle what is this
one periodic time
when oscillations are out phase when 2 waves have the same frequency what can they be
in or out of phase
