JEE Main PYQ — Dual Nature of Matter and Radiation
Previous-year questions from the JEE Main paper, in the exact form they were asked, together with original practice pitched at the same level. Every question carries a full step-by-step solution that shows the method and names the trap it sets.
Questions marked Numeric Answer Type are the typed-answer kind: in the exam you enter the value yourself rather than choose from four options. They are shown here with options only so you can check yourself.
Nothing in this section repeats Sections 1-5.
Tip. Photon energy depends on frequency alone; intensity only changes how many photons arrive. Work under time pressure — about two minutes a question — before you read any solution.
