Linear Magnification
JEE Main asked Linear Magnification 3 times in 3 of the 108 shifts Lumi analysed, in 2021, 2024 and 2025. It belongs to Spherical Mirrors, in Ray Optics and Optical Instruments (Physics). The longest wait between two years asking it was 3 years.

Questions on this idea a shift, by year
2017–2026. Asked in 2021, 2024 and 2025. 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: 1 in 24 shifts · 2022: 0 in 24 shifts · 2023: 0 in 12 shifts · 2024: 1 in 18 shifts · 2025: 1 in 8 shifts · 2026: 0 in 9 shifts.
