NEET 2025 Physics Questions
Use this page to connect the official 2025 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.
Original practice preview
These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 2 · difficulty 4/5
For the hydrogen spectrum, the ratio of the shortest wavelength (series limit) of the Balmer series to that of the Lyman series is:
- A. 1 : 4
- B. 2 : 1
- C. 1 : 1
- D. 4 : 1
Example 3 · difficulty 1/5
In a photoelectric experiment, monochromatic light of frequency greater than the threshold frequency falls on a metal plate. If the intensity of this light is doubled while its frequency is kept unchanged, then:
- A. the saturation photocurrent doubles but the stopping potential remains unchanged
- B. the stopping potential doubles but the saturation photocurrent remains unchanged
- C. both the saturation photocurrent and the stopping potential double
- D. the saturation photocurrent doubles but the stopping potential is halved
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 2025 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 2025 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.
