NEET 2026 Physics Modern Physics Questions

Use this page to connect the official 2026 paper with current Physics practice. NeetVellum does not claim a chapter appeared in that paper until the official question and final key have been mapped.

What to master

photoelectric effect, atomic models, spectra, nuclei and radioactivity.

Original practice preview

These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.

Example 1 · difficulty 2/5

The stopping potential in a photoelectric experiment is best described as the

A. largest positive collector potential at which saturation begins
B. potential difference that gives the greatest photocurrent
C. minimum retarding potential magnitude that reduces the photocurrent to zero
D. potential of the emitter when no radiation is incident

Example 2 · difficulty 1/5

For a given photosensitive material, threshold frequency is the

A. frequency at which the photocurrent is always saturated
B. highest frequency that can be reflected by the metal
C. frequency for which emitted electrons have the greatest possible kinetic energy
D. minimum incident frequency below which photoelectric emission does not occur

Example 3 · difficulty 3/5

A metal has threshold frequency 6.0 × 10¹⁴ Hz. What is its threshold wavelength? Use c = 3.0 × 10⁸ m s⁻¹.

A. 500 nm
B. 200 nm
C. 600 nm
D. 1800 nm

The evidence-first practice loop

1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
2. Attempt closed-bookExpose the concept or execution gap before rereading.
3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions

Are these official NEET 2026 Physics Modern Physics PYQs?

No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.

How should I use the NEET 2026 paper?

Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
