In a standing wave formed by two atoms separated by 1.21Å,` there are 3 nodes and 2 antinodes. Find its wavelength.

A

`1.21 Å`

B

`2.42Å`

C

`6.05Å`

D

`3.63Å`

Text Solution

Verified by Experts

The correct Answer is:
A

Here n= no.of closed loops = no. of antinodes =2
Now, `lamda _(n) = (2L)/(n) = ( 2 xx 1.21 )/(2) 1.21 Å`

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

Assume that the de-Brogile wave associated with an electron can form a standing wave between the atoms arranged in a one dimensional array with nodes at wach of the atomic sites. If is found that one such standing wave is formed if the distance 'd' between the atoms of the array is 2Å . A similar wave in again formed if 'd' is increased to 2.5 A but not for any intermediate value of d. Find the energy of the electrons in electron volts and the least value of d for which the standing wave of the standing wave of the type described above can form.
