NEET 2016 Physics Ray Optics Questions
Use this page to connect the official 2016 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
mirrors, lenses, refraction, optical instruments and sign-convention discipline.
Original practice preview
These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 2 · difficulty 3/5
An object is placed 30 cm in front of a thin convex lens of focal length 20 cm. The image formed is:
- A. 60 cm behind the lens, real, inverted and twice as tall as the object
- B. 12 cm in front of the lens, virtual, erect and diminished
- C. 60 cm in front of the lens, virtual, erect and magnified
- D. 12 cm behind the lens, real, inverted and diminished
Example 3 · difficulty 3/5
A ray passes through a prism of refracting angle 60° at minimum deviation of 30°. The refractive index of the prism material is closest to:
- A. 1.33
- B. 1.50
- C. 1.73
- D. 1.41
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 2016 Physics Ray Optics 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 2016 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.
