In a stationary wave, the distance between a node and an adjacent antinodes is equal to?
Correct answer: D. λ/4
- A. λ
- B. 2λ
- C. λ/2
- D. λ/4
Explanation
Option A : In a stationary wave, the distance between an adjacent node and antinode is not ƛ. Option B .: In a stationary wave, the distance between an adjacent node and antinode is not 2ƛ. Option C : In a stationary wave, the distance between an adjacent node and antinode is not ƛ/2.Option : D In stationary wave, the distance between node to node or antinode to antinode is ƛ/2 while the distance between node to antinode is ƛ/4.

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.
