Dual Nature of Radiation and Matter — NEET/JEE Questions, Notes & Weightage
Class 12 Modern Physics NEET weightage: High 139 questions
Covers the photoelectric effect, Einstein's photoelectric equation, and de Broglie wavelength. Photoelectric-effect numericals (finding stopping potential, work function, or threshold frequency) are tested almost every year.

Frequently asked questions
What is the most-tested numerical here?
Using Einstein's photoelectric equation to find the stopping potential, maximum kinetic energy, or work function given the incident light's frequency/wavelength is the chapter's signature question type.
Is de Broglie wavelength tested directly?
Yes — calculating the de Broglie wavelength of an electron or particle given its momentum or accelerating voltage is a standard, recurring numerical.
