In a stationary wave, the distance between a node and an adjacent antinode is equal to:
Correct answer: D. λ/4
- A. λ
- B. 2λ
- C. λ/2
- D. λ/4
Explanation
The distance between successive nodes is half wavelength whereas the distance between a node and an antinode is quarter of a wavelength.

About Stationary Waves
Stationary waves form when two waves of the same frequency and amplitude travel in opposite directions and interfere. The topic covers nodes, antinodes, wavelength, phase, resonance, and the allowed frequencies on strings and in air columns. Unlike progressive waves, stationary waves do not transfer energy from one point to another.
