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 1 · difficulty 3/5

Two sound waves of the same frequency travelling in the same direction have intensities in the ratio 9 : 1. When they superpose, the ratio of the maximum to the minimum intensity of the resultant wave is:

A. 2 : 1
B. 4 : 1
C. 3 : 1
D. 9 : 1

Example 2 · difficulty 2/5

At the same temperature, the ratio of the speed of sound in hydrogen to that in oxygen is (molar masses: H₂ = 2 g mol⁻¹, O₂ = 32 g mol⁻¹; both gases are diatomic):

A. 1 : 4
B. 1 : 16
C. 16 : 1
D. 4 : 1

Example 3 · difficulty 1/5

In a transverse mechanical wave moving through a medium, how is the displacement of a medium particle oriented relative to the direction of wave propagation?

A. Perpendicular to the direction of wave propagation
B. Parallel to the direction of wave propagation
C. Always vertically upward
D. Along the direction of propagation only at a crest

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 2018 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 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.
