Stopping Potential

JEE Main asked Stopping Potential 4 times in 4 of the 108 shifts Lumi analysed, in 2021 and 2024. It belongs to Photoelectric Effect, in Dual Nature of Radiation and Matter (Physics). The longest wait between two years asking it was 3 years. In 2021 and 2024 it came in more than one shift of the same year.

Questions on this idea a shift, by year

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