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

`1.21 Å`

`1.40 Å`

`6.05 Å`

`3.63 Å`

Text Solution

Verified by Experts

The correct Answer is:

The given standing wave is shown in the figure.

As the length of one loop segment is ` ( lamda ) /( 2 )`
so length of 2 segments is ` 2 ( (lamda )/ (2 )) `
` therefore 2 ( lamda )/( 2) = 1.4 Å rArr lamda = 1.4 Å `

In a standing wave 4 nodes and 3 antinodes are formed between two fixed end of string of length 6 m. Then the wave length of the standing wave is

The string fixed at both ends has standing wave nodes for which distance between adjacent nodes is x_1 . The same string has another standing wave nodes for which distance between adjacent nodes is x_2 . If l is the length of the string then x_2//x_1=l(l+2x_1) . What is the difference in numbers of the loops in the two cases?
