Modern Physics PYQs — JEE Main & Advanced, fully solved
Photoelectric effect, dual nature, Bohr model, hydrogen spectrum, nuclear physics, radioactivity and semiconductors — chapter-wise PYQs with step-by-step solutions.
Modern Physics is the most scoring chapter cluster in JEE Physics — short formulas, repetitive patterns and 8–12 marks every JEE Main attempt.
IITMentor collects every Modern Physics PYQ from the last 25+ years and pairs each with the formula, substitution and the trap (sign of energy, units of work function, etc.) so you never lose marks to silly mistakes.
Built to move your JEE rank — not just to look pretty

Frequently asked
What does Modern Physics include for JEE?
+
Photoelectric effect, dual nature, atomic structure (Bohr model, hydrogen spectrum), nuclear physics, radioactivity and semiconductor electronics — all of Class 12 Modern Physics.
How many marks does Modern Physics carry in JEE Main?
+
Modern Physics consistently contributes 8–12 marks in JEE Main and 1–2 questions in JEE Advanced — high yield with relatively shorter prep time.
Are Modern Physics PYQs solved with formulas?
+
Yes — every PYQ shows the relevant formula (de Broglie, Bohr radius, work function), the substitution and the trap (units, sign of energy, etc.).
Which is the most scoring topic in Modern Physics?
+
Photoelectric effect and Bohr model — short formulas, predictable question patterns, easy 4–8 marks if PYQs are solved twice.
