Official Correct Choice:
Option B: 0.01 s
Concept:

Time period (\( T \)) is the time required to generate exactly one complete wave. It is the reciprocal of frequency (\( f \)).

Formula:

$$ f = \frac{\text{Waves}}{\text{Time}} \quad \text{and} \quad T = \frac{1}{f} $$

Solution:

  • Alternatively, calculate time period directly: \( T = \frac{\text{Total Time}}{\text{Number of Waves}} \).


  • Substitute the given values: \( T = \frac{10 \text{ seconds}}{1000 \text{ waves}} \).


  • \( T = \frac{1}{100} = 0.01 \text{ s} \).


Why other options are incorrect:

Option A comes from dividing 1 by 1000, ignoring the 10-second duration. Option D assumes only 100 waves were generated.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
