Original practice preview

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

Example 1 · difficulty 2/5

The displacement of a wave is y = A sin(6x + 24t), with SI units understood. In which direction and at what speed does it travel?

A. Positive x-direction at 4 m s⁻¹
B. Negative x-direction at 18 m s⁻¹
C. Positive x-direction at 30 m s⁻¹
D. Negative x-direction at 4 m s⁻¹

Example 2 · difficulty 2/5

Two points lie 0.30 m apart along the direction of a wave whose wavelength is 0.40 m. What is the spatial phase increment kΔx between them?

A. 3π/2 rad
B. π/2 rad
C. 3π/4 rad
D. 2π rad

Example 3 · difficulty 2/5

At a fixed position, what is the magnitude of the phase change of a sinusoidal wave during a time interval equal to one-eighth of its period?

A. π/8 rad
B. π/4 rad
C. π/2 rad
D. 2π rad

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 2021 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 2021 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.
