In the ground state of a hydrogen atom,an electron absorbs $1.5$ times the minimum energy $\left(2.18 \times 10^{-18} \ J\right)$ required to escape from the atom. The wavelength of the emitted electron (in $m$) is $\left(m_e = 9 \times 10^{-31} \ kg\right)$.

  • A
    $\frac{h \times 10^{24}}{\sqrt{1.962}}$
  • B
    $\frac{h}{\sqrt{1.962}} \times 10^{23}$
  • C
    $\frac{h}{\sqrt{1.962}} \times 10^{25}$
  • D
    $\frac{h}{\sqrt{1.962}} \times 10^{22}$
