The question is: "Two travelling waves are superposed on the same string. Waves are y1=Asin (ωt−kx) and y2=Asin(ωt+kx).The distance between adjacent nodes of the resulting standing wave is: "(adsbygoogle = window.adsbygoogle || []).push({});

This is the question I have tried to solve.

I know that the distance between two nodes is 2pii. Then I do not know how to proceed.

The answer is pii/k,

but I do not know how it is obtained.

Please, do not hesitate to reply if you know why the answer is pii/k.

Thank you in advance!
