hello guys

can someone pleaseee explain phase difference fully, i never seem to understand it properly, and please do question 5 (a), Nov 07

thanks :)

nid404:
Phase difference is the difference between corresponding points of two waves measured in terms of

Sorry for that crappy drawing attached

Anyway this should give you an idea

[Spy]:
the said the intensity is halved now, so the amplitude has to change?

and im sorry, i dont really understand you got what you drew. i mean do you make each pie revolution, into a third?

nid404:
I didn't notice the amplitude...sorry :P

half the wavelength= pi radians

pi radians=180 degrees

so 60 degrees is pi/3

[Spy]:
yeah okay i understand that party, but i mean how did you draw it exactly? godd i hate wavess!!!
