The ratio of the nodes and antinodes in a closed pipe system (open at one end) is always:
Correct answer: B. Greater than one
- A. Less than one
- B. Greater than one
- C. Equal to one
- D. Less than or equal to one
Explanation
For a pipe closed at one end, modes have node at closed end and antinode at open end; typically number of nodes exceeds antinodes (nodes = antinodes +1), so ratio nodes/antinodes > 1.

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
