Which one of the following statements most accurately applies to the frequency of a waveform? A. The actual frequency of a sine waveform is 1.41 times the working frequency B. Unless specified otherwise, the frequency of a waveform is assumed to be 60 Hz C. The higher the amplitude of a waveform, the higher its frequency D. The longer the period of a waveform, the lower its frequency E. None of the above

The correct answer is: D. The longer the period of a waveform, the lower its frequency.

Frequency is the number of

cycles per unit time. It is measured in hertz (Hz), which is equal to one cycle per second. The period of a waveform is the time it takes for one cycle to complete. The higher the frequency, the shorter the period.

Option A is incorrect because the actual frequency of a sine waveform is equal to the working frequency.

Option B is incorrect because the frequency of a waveform is not assumed to be 60 Hz unless specified otherwise.

Option C is incorrect because the amplitude of a waveform does not affect its frequency.

Option E is incorrect because all of the other options are incorrect.
