2 sinusiodal waves are defined(adsbygoogle = window.adsbygoogle || []).push({});

y1=2sin(20x-32t)

y2=2sin(25x-40t)

what is the phase difference between this two waves at point x=5 and t=2s. all length in cm.

I sketch the graph y/x and y/t and both have their max amplitude at x=3.2 , and t=3.125s.

so what is the different in phase? Arn't them in phase?
