Closed Organ Pipe Harmonics

JEE Main asked Closed Organ Pipe Harmonics 4 times in 4 of the 108 shifts Lumi analysed, in 2021, 2022, 2023 and 2024. It belongs to Resonance in Air Columns, in Waves (Physics). The longest wait between two years asking it was 1 year.

Questions on this idea a shift, by year

2017–2026. Asked in 2021, 2022, 2023 and 2024. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
