NEET 2017 Physics Waves Questions
Use this page to connect the official 2017 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
wave equations, sound, standing waves, beats and Doppler effect.
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.
