    Question

    The energy of a photon is proportional

    to:
    A Its wavelength Correct Answer Incorrect Answer
    B Its speed Correct Answer Incorrect Answer
    C Its frequency Correct Answer Incorrect Answer
    D Its amplitude Correct Answer Incorrect Answer

    Solution

    The energy of a photon is given by E=hnuE = h\\nuE=hnu, where hhh is Planck’s constant and nu\\nunu is the frequency. Thus, photon energy is directly proportional to frequency.
