How to Use the Dual Nature of Radiation and Matter PYQ PDF for MHT CET

Start with the 2025 and 2026 papers first, because they hold 64 of the 163 questions.
Keep K_max = hν - φ and eV₀ = K_max together, since most of the photoelectric questions start from them.
For the de Broglie ratio, write λ = h/√(2mqV) and cancel the common terms.
Solve year-wise PYQs by timing yourself, as time management is crucial.
Re-attempt only the questions you got wrong, and note which formula or step you missed.
