Question

    Which property of a wave is related to its

    frequency?  
    A Speed Correct Answer Incorrect Answer
    B Wavelength Correct Answer Incorrect Answer
    C Amplitude Correct Answer Incorrect Answer
    D Energy Correct Answer Incorrect Answer

    Solution

    The energy of a wave is directly proportional to its frequency.   The higher the frequency, the higher the energy.   This is true for electromagnetic waves such as light.   Energy  E  is given by the formula E = h × f, where h  is Planck's constant and f  is frequency.
