If $a_{0}$ be the radius of first Bohr's orbit of H -atom, then de-Broglie's wavelength of an electron revolving in $3^{rd}$ Bohr's orbit will be -

Answer:

Solution:

$2 π r = n λ_{d}$

$2 π a_{0} \frac{n ^{2}}{z} = n λ_{d}$

$2 π a_{0} \times \frac{3 ^{2}}{1} = 3 λ_{d}$

$λ_{d} = 6 π a_{0}$ [In 3rd orbit]
