Q. Which is the correct relation between de-Broglie wavelength of an electron in the $n^{\text {th }}$ Bohr orbit and radius of the orbit $R ?$
Atoms
A
$\lambda=n 2 \pi R$
B
$\lambda=\frac{2 \pi R}{n}$
C
$\lambda=\frac{4 \pi R}{n}$
D
$\lambda=\frac{2 \pi R}{n h}$
Solution:
$\lambda=\frac{h}{m v}$ in $2 \pi r_{n}=\frac{n h}{m v_{n}}$
