NEET 2024 Physics Questions
Use this page to connect the official 2024 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 1/5
A sample of hydrogen atoms is excited to the n = 5 level. As the atoms return to the ground state, the maximum number of distinct emission spectral lines that can be observed is:
- A. 4
- B. 6
- C. 10
- D. 15
Example 3 · difficulty 2/5
de Broglie offered a physical picture of Bohr's second postulate (quantisation of angular momentum). According to this interpretation, a permitted electron orbit in the hydrogen atom is one in which:
- A. the electron moves with uniform drift velocity set by the applied field
- B. the circumference of the orbit equals an integral multiple of the electron's de Broglie wavelength
- C. the orbit is an ellipse with the nucleus at its geometric centre
- D. the de Broglie wavelength keeps decreasing continuously as the electron goes round the loop
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 2024 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 2024 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.
