  • question_answer
    The linear momentum of photon is p. The wavelength of photon is \[\lambda \], then (\[h\]is Planck?s constant)

    A)  \[\lambda =hp\]

    B)  \[\lambda =\frac{h}{p}\]

    C)  \[\lambda =\frac{p}{h}\]

    D)  \[\lambda =\frac{{{p}^{2}}}{h}\]

    Correct Answer: B

    Solution :

     Momentum of photon, \[p=\frac{h}{\lambda }\] Therefore, wavelength of photon, \[\lambda =\frac{h}{p}\]
