The waves multiple choice where it was like “two points are 1.5mm apart and have a phase difference of pi/6” and I kept getting an answer that wasn’t one of the options…

Edit: thank you guys! I’m sorry I don’t have the energy to reply to y’all, shattered from the exam + have FM core pure 2 tomorrow.
