    If h is the Plancks constant, the momentum of a photon of wavelength 0.01 \[\overset{0}{\mathop{A}}\,\] will be :

    A) \[{{10}^{-3}}h\]                                

    B) \[{{10}^{11}}h\]

    C)  \[{{10}^{13}}h\]                                              

    D) \[{{10}^{12}}h\]

    Correct Answer: D

    Solution :

    Given, \[\lambda =0.01\overset{\text{o}}{\mathop{\text{A}}}\,=0.01\times {{10}^{-10}}={{10}^{-12}}m\] Momentum of photon is given by \[p=\frac{h}{\lambda }=\frac{h}{{{10}^{-12}}}={{10}^{12}}h\]
