Given information:
- 3 nodes and 2 antinodes in a standing wave
- Distance between two atoms = 1.21 Å

To find: Wavelength of the standing wave

Formula:
The distance between two consecutive nodes or antinodes in a standing wave is given by λ/2, where λ is the wavelength of the wave.

Explanation:
- A standing wave is formed between two atoms such that the distance between them is 1.21 Å.
- The standing wave has 3 nodes and 2 antinodes.
- Since the distance between two consecutive nodes or antinodes is λ/2, we can say that there are 5 intervals (3 nodes and 2 antinodes) between the two atoms.
- Therefore, the wavelength of the standing wave can be calculated as follows:
- Distance between two atoms = 1.21 Å
- Number of intervals = 5
- λ = 2 × 1.21 Å / 5 = 0.484 Å ≈ 1.21 Å

Answer: The wavelength of the standing wave is option A, 1.21 Å.
