Asked by Bashr

Two identical traveling waves, moving in the same direction, are out of phase by PI/3.0 rad. What is the amplitude of the resultant wave in terms of the common amplitude ym of the two combining waves? (Give the answer as the ratio of the total amplitude to the common amplitude.)
Thanks in Advance
