Image Velocity (Axial Motion)
JEE Main asked Image Velocity (Axial Motion) 3 times in 3 of the 108 shifts Lumi analysed, in 2020, 2021 and 2023. It belongs to Spherical Mirrors, 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 2020, 2021 and 2023. 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: 1 in 12 shifts · 2021: 1 in 24 shifts · 2022: 0 in 24 shifts · 2023: 1 in 12 shifts · 2024: 0 in 18 shifts · 2025: 0 in 8 shifts · 2026: 0 in 9 shifts.
