  • question_answer
    If the momentum of a photon is p, then its frequency is [MP PET 1989]

    A)            \[\frac{ph}{c}\]                   

    B)            \[\frac{pc}{h}\]

    C)            \[\frac{mh}{c}\]                  

    D)            \[\frac{mc}{h}\] Where m is the rest mass of the photon

    Correct Answer: B

    Solution :

               \[p=\frac{E}{c}=\frac{h\nu }{c}\,\Rightarrow \,\,\nu =\frac{pc}{h}\]
