Lateral Shift in Slabs
JEE Main asked Lateral Shift in Slabs 2 times in 2 of the 108 shifts Lumi analysed, in 2022 and 2024. It belongs to Refraction and Snell's Law, in Ray Optics and Optical Instruments (Physics). The longest wait between two years asking it was 2 years.

Questions on this idea a shift, by year
2017–2026. Asked in 2022 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: 1 in 24 shifts · 2023: 0 in 12 shifts · 2024: 1 in 18 shifts · 2025: 0 in 8 shifts · 2026: 0 in 9 shifts.
