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

A

`3.63Å`

B

`6.05Å`

C

`1.12Å`

D

`2.42 Å`

Text Solution

Verified by Experts

The correct Answer is:
C
Two loops contains 3 nodes and 2 antinodes (with node at end)
`p((lambda)/(2)) = L or 2 xx (lambda)/(2) = L`
`lambda = 1.21 Å`

A standing wave having 3 nodes and 2 antinodes are formed between two rigid supports of length 1m. Then the wavelength of the standing wave is

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?

For a certain transverse standing wave on a long string , an antinode is formed at x = 0 and next to it , a node is formed at x = 0.10 m , the displacement y(t) of the string particle at x = 0 is shown in Fig.7.97.
