Original practice preview

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

Example 1 · difficulty 1/5

Which observation made by Hertz provided an early indication of the photoelectric effect?

A. Ultraviolet light falling on the negative electrode made sparking across a gap easier
B. Infrared light falling on a metal increased its electrical resistance
C. Visible light passing through vacuum produced an electric current without electrodes
D. Ultraviolet light increased the mass of a positively charged electrode

Example 2 · difficulty 2/5

In Hallwachs’ experiment, ultraviolet light is directed onto a freshly cleaned zinc plate. Which observation correctly describes the result?

A. A positively charged plate is discharged because positive charges leave it
B. A negatively charged plate loses its charge, while a positively charged plate is not similarly discharged
C. Both positively and negatively charged plates are discharged at identical rates
D. An initially uncharged plate necessarily becomes negatively charged

Example 3 · difficulty 2/5

Why is the photoelectric tube used in Lenard-type investigations evacuated?

A. To raise the threshold frequency of the emitter
B. To prevent light from reaching the collector
C. To reduce collisions of emitted electrons with gas molecules
D. To make the collector emit electrons thermally

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 2024 Physics Modern Physics 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 2024 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.
