Comparative Graphs for Different Metals
JEE Main asked Comparative Graphs for Different Metals 2 times in 2 of the 108 shifts Lumi analysed, in 2024 and 2026. It belongs to Photoelectric Effect, in Dual Nature of Radiation and Matter (Physics). The longest wait between two years asking it was 2 years.

Questions on this idea a shift, by year
2017–2026. Asked in 2024 and 2026. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
Raw count: 2017: 0 in 1 shift · 2020: 0 in 12 shifts · 2021: 0 in 24 shifts · 2022: 0 in 24 shifts · 2023: 0 in 12 shifts · 2024: 1 in 18 shifts · 2025: 0 in 8 shifts · 2026: 1 in 9 shifts.
