If an electron,hydrogen nucleus,helium nucleus,and neon nucleus are all moving with the same velocity,then the wavelengths associated with these particles are in the order:
- A$Electron > Hydrogen > Helium > Neon$
- B$Electron > Helium > Hydrogen > Neon$
- C$Electron < Hydrogen < Helium < Neon$
- D$Neon < Hydrogen < Helium < Electron$

View SolutionIf $a_0$ is denoted as the Bohr radius of the hydrogen atom,then what is the de-Broglie wavelength $(\lambda)$ of the electron present in the $n^{th}$ orbit of the hydrogen atom?
An electron has kinetic energy $2.8 \times 10^{-23} \ J$. The de-Broglie wavelength will be nearly $(m_e = 9.1 \times 10^{-31} \ kg)$.
