Original practice preview

These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.

Example 1 · difficulty 1/5

A. u positive, v positive, f positive
B. u negative, v positive, f negative
C. u negative, v negative, f negative
D. u positive, v negative, f positive

Example 2 · difficulty 1/5

For every finite position of a real object in front of a convex mirror, the image formed is

A. real, inverted, and enlarged
B. real, inverted, and diminished
C. virtual, inverted, and enlarged
D. virtual, erect, and diminished

Example 3 · difficulty 2/5

A concave mirror forms an image at v = −30 cm of an object at u = −15 cm. What is the transverse magnification?

A. +2
B. −2
C. +0.5
D. −0.5

Frequently asked questions

Are these official NEET 2018 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 2018 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.
