K_max versus Frequency Graph
JEE Main asked K_max versus Frequency Graph 2 times in 2 of the 108 shifts Lumi analysed, in 2023 and 2024. It belongs to Photoelectric Effect, in Dual Nature of Radiation and Matter (Physics). The longest wait between two years asking it was 1 year.

Questions on this idea a shift, by year
2017–2026. Asked in 2023 and 2024. 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: 1 in 12 shifts · 2024: 1 in 18 shifts · 2025: 0 in 8 shifts · 2026: 0 in 9 shifts.
