NEET 2019 — Displacement Current (Confirmed) Question type: "Displacement current between capacitor plates is due to ____." Correct: changing electric field. Wrong traps offered: electron flow, positive ion drift, static field. Strategy: Memorise "Id = ε{0}(dΦ_E/dt) = NOT real charge flow."

NEET 2020 — EM Spectrum Applications (Confirmed) Question type: "Which EM wave is used for radar?" (Microwaves) and "Which wave produces heat when absorbed by water?" (Microwaves cause molecular rotation). Strategy: Memorise application-wave type pairings completely.

NEET 2022 — EM Wave Properties (Confirmed) Question type: "In an EM wave, E and B fields are _____." Traps: "perpendicular and out of phase" (wrong — they are in phase), "parallel and in phase" (wrong on both counts). Strategy: E ⊥ B ⊥ propagation (spatial), but in phase (temporal).

NEET 2023 — X-ray vs Gamma (Style) Question type: "Two EM radiations with frequencies in the range 10^{19} Hz — one from an X-ray tube, one from nuclear decay — are _____." Answer: the first is X-ray, second is gamma ray, both in overlapping range. Strategy: Source-based classification is the key.

High-Frequency PYQ Topics (rank order):

1. EM spectrum applications — almost every year; 1–2 questions
2. Speed of EM waves in vacuum — 1 question every year
3. E–B relationship — every 2 years
4. Displacement current — every 2–3 years
5. Radiation pressure/momentum — occasionally

Time Allocation Strategy for 2026 NEET:

• Memorise application table (5 min)
• Recall mnemonic RMIVU-X-G
• Know displacement current formula and its physical meaning
• Know $E_{0}$/$B_{0}$ = c and I = (1/2)ε_{0}c$E_{0}^{2}$ formulas
• Practice 2–3 numerical examples for intensity and displacement current
