Question

The angular momentum of electron in H atom in \(n_x\) state is \(1.051\times10^{-34}\,\mathrm{J\,s}\). The de Broglie wavelength of electron in this \(n_x\) state is \[ (h=6.6\times10^{-34}\,\mathrm{J\,s};\ \pi=3.14) \]

• A. \(33.2\times10^{-2}\,\mathrm{nm}\)
• B. \(66.4\times10^{-2}\,\mathrm{nm}\)
• C. \(332.1\times10^{-2}\,\mathrm{nm}\)
• D. \(662.4\times10^{-2}\,\mathrm{nm}\)

Hint:

For Bohr's model, \[ \boxed{ L=n\frac{h}{2\pi} } \] and \[ \boxed{ 2\pi r_n=n\lambda. } \]

Answer 1
