180°----15 boxes
60°-----x
u cross multiply and get x as 5 boxes
then from each point of the original wave u count 5 boxes and make a mark
then join all ur marks to get a wave with phase diff 60°.

hope that helps!

Thank you very much for the answer...i was also able to get 60 deg equals 5 boxes..but the worl lags behind confused me....I am still confused ..is the second wave laging or leading in ur picture?

the wave is lagging!!
see the x-axis is for time, the original wave starts frm 0 sec while the new wave starts 0.5sec after this wave..so therefore its lagging

thank you very much i was confused with the word lagging...now i am clear...thanks dude

the one that completes itself late is lagging!
