The distance between the node and the next anti-node is:
Correct answer: A. λ/4
- A. λ/4
- B. λ
- C. λ/2
- D. 2λ
Explanation
In a standing wave, node to adjacent antinode is one quarter wavelength (λ/4). Thus option A is correct.

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.
