This is a short answer type question as classified in NCERT Exemplar
We have to observe the displacement and position of different points, then accordingly nature of two waves decided
Points on positions x= 10,20,30,40 never move, always at mean position with respect to time . these are forming nodes which forms a stationary wave
Distance between two successive nodes =
node to node distance)
=2 (20-10)
= 2 (10)=20cm
