    若光子的波长和电子的德布罗意波长`\lambda`相等,试求光子的质量与电子的质量之
    比.`m_{0}`为电子的静止质量.
    A: `\frac{1}{\sqrt{1+m_{0}^{2}c^{2}}`
    B: `\frac{1}{\sqrt{1-m_{0}^{2}c^{2}}`
    C: `\frac{1}{\sqrt{1-(m_{0}^{2}\lambda^{2}c^{2}/h^{2})}`
    D: `\frac{1}{\sqrt{1+(m_{0}^{2}\lambda^{2}c^{2}/h^{2})}`
    E: `\sqrt{1+(m_{0}^{2}\lambda^{2}c^{2}/h^{2})}`
    F: `\sqrt{1-(m_{0}^{2}\lambda^{2}c^{2}/h^{2})}`
