Well I want to clarify some doubts regarding the calculation of
phase difference. I understand that there are some formula we can
use such as t/T X 2pi or x/wavelength X 2pi to calculate phase
difference.
However, if we were given graphs of x-t, v-t, and a-t graphs
(representing displacement, velocity and acceleration respectively)
and let's say we have to find the phase difference between x-t and
v-t graphs, can we draw the 2 graphs one below the other (let's put
the x-t graph on the top and v-t graph below) and at the point
where the x-t graph has a CREST, we draw a VERTICAL line all the
way down to the v-t graph... and next we look out for the next
CREST on the v-t graph, draw a line from the crest up the the x-t
graph above? Then we compare the time difference between the two
and determine the phase difference? (eg. 1/2 wavelength apart
between crest of x-t and crest of v-t means a phase diff of pi)
Is this method correct? I know it sounds confusing to describe
but I have already tried my best to explain my method of
determining phase diff. Hope someone can point out if my method is
valid. Thanks.
