A standing wave having 3 nodes and 2 antinodes is formed between two atoms having a distance 1 . 21 A ∘ between them. The wavelength of the standing wave is

The given standing wave is shown in the figure As the length of loop or segment is λ 2 So the length of 2 segments is 2 λ 2 ∴ 2 λ 2 = 1.21 A ∘ ⟹ λ = 1.21 A ∘

A standing wave having $3$ nodes and $2$ antinodes is formed between two atoms having a distance $1.21 \overset{\circ}{A}$ between them. The wavelength of the standing wave is

Options:

Answer:

Solution:

The given standing wave is shown in the figure

As the length of loop or segment is $\frac{λ}{2}$

So the length of 2 segments is $2 (\frac{λ}{2})$

$∴ 2 \frac{λ}{2} = 1.21 \overset{\circ}{A}$

$⟹ λ = 1.21 \overset{\circ}{A}$
