The diagram shows a second harmonic standing wave on a string fixed at both ends.
What is the phase difference, in rad, between the particle at X and the particle at Y?

[@youssefabed2024]

Key idea to take away, "In the case of standing waves, only two phase differences are possible. Either the phase difference between two particles can be zero or it can be Pi. And seeing how none of the options are Pi, you can automatically select 0 without thinking further. Great explanation Varun as always!
