An electron of mass m and a photon have same energy E. The ratio of de-Broglie wavelengths associated with them is :

  • Option 1)

    \frac{1}{c}\left(\frac{\text{E}}{2\text{m}}\right)^{\frac{1}{2}}

  • Option 2)

    \left(\frac{\text{E}}{2\text{m}}\right)^{\frac{1}{2}}

  • Option 3)

    c\left(2\text{mE}\right)^{\frac{1}{2}}

  • Option 4)

    \frac{1}{c}\left(\frac{2\text{m}}{\text{E}}\right)^{\frac{1}{2}}
