A standing wave having 3 nodes and 2 antinodes is formed between two atoms having a distance 1.21 Å Å between them. The wavelength of the standing wave is

Options

  1. A1.21 Å
  2. B1.42 Å
  3. C6.05 Å
  4. D3.63 Å

Correct answer

A. 1.21 Å

Step-by-step solution

Key Idea The given standing wave has 2 segments. The given standing wave is shown in the figure. As length of one loop or segment is 2 , so length of 2 segments is 2 ( 2 ) . 2 2 =1.21 Å =1.21 Å
