If the radius of first orbit of $H$ atom is $a_{0}$ , the deBroglie wavelength of an electron in the third orbit is

Options:

Answer:

Solution:

$r_{n} = a_{0} n^{2}$ $r = a_{0} \times (3)^{2} = 9 a_{0} m v r = \frac{nh}{2 π} m v = \frac{nh}{2 π r} = \frac{3 h}{2 π \times 9 a _{0}} = \frac{h}{6 π a _{0}} λ = \frac{h}{m v} = \frac{h}{h} \times 6 π a_{0} = 6 π a_{0}$
