Two identical travelling waves, moving in the same direction, are out of phase by Pi/2 rad.(adsbygoogle = window.adsbygoogle || []).push({});

(a) What is the ratio of the amplitude of the resultant wave to that of the common amplitude of the waves

I'm having trouble with this problem because I feel like I'm not given enough information, although I know that's not really the case. Does anyone have any recommendations as to where I can look up some information that can help me with this problem?
