Calculate the de-Broglie's wavelength of an electron residing in the 2nd Bohr's orbit of a hydrogen atom. (Bohr's radius, \(a_0=0.529 Å\) )
- A 0.2116 nm
- B \(2.116 \pi Å\)
- C 21.16 m
- D 2.116 μm
Answer & Solution
Correct Answer
(B) \(2.116 \pi Å\)
Step-by-step Solution
Detailed explanation
Bohr’s radius is equal to most probable distance between the nuclear and electron in H-atom in its ground states. According to de-Broglie wavelength, the allowed any stationary orbit i.e. \(n \lambda=2 \pi r\)…
