Original practice preview

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

Example 1 · difficulty 2/5

Why are rays close to the principal axis and making small angles with it used to obtain the standard spherical-mirror formula?

A. Such rays experience no reflection
B. They make the paraxial approximation valid and reduce spherical aberration effects
C. They force every image to be virtual
D. They change a spherical mirror into a plane mirror

Example 2 · difficulty 3/5

A vessel viewed normally from air contains a 6 cm layer of glass of refractive index 1.5 above an 8 cm layer of water of refractive index 4/3. What is the apparent depth of the bottom measured from the top surface?

A. 14 cm
B. 9 cm
C. 10 cm
D. 21 cm

Example 3 · difficulty 3/5

A point object in air is 60 cm from a convex spherical surface of glass. The refractive index of glass is 1.5 and the radius of curvature is 20 cm, with the centre of curvature inside the glass. Using the Cartesian sign convention, where is the image formed?

A. 180 cm inside the glass
B. 120 cm inside the glass
C. 60 cm inside the glass
D. 180 cm on the object side

Frequently asked questions

Are these official NEET 2023 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 2023 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.
