Original practice preview
These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 2 · difficulty 3/5
A tuning fork of unknown frequency produces 4 beats per second with a standard fork of frequency 256 Hz. When a little wax is attached to the unknown fork, the beat frequency increases to 6 per second. The original frequency of the unknown fork was:
- A. 252 Hz
- B. 260 Hz
- C. 250 Hz
- D. 262 Hz
Example 3 · difficulty 4/5
A train whistle emitting sound of frequency 400 Hz approaches a cyclist at 20 m s⁻¹, while the cyclist pedals towards the train at 10 m s⁻¹. Taking the speed of sound in air as 340 m s⁻¹, the apparent frequency heard by the cyclist is:
- A. 412.5 Hz
- B. 425 Hz
- C. 437.5 Hz
- D. 400 Hz
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 2017 Physics Waves 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 2017 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.
