Final answer:
The frequency of a sinusoidal voltage waveform is the number of cycles per second, measured in Hertz (Hz), and it is the reciprocal of the period (the time it takes for one wave cycle to complete). The correct answer is option C.
Step-by-step explanation:
The frequency of a sinusoidal voltage waveform is defined as the number of cycles per second. This is the rate at which the waveform repeats itself and is measured in Hertz (Hz). The time required for one complete cycle of the waveform is its period (T), and frequency (f) is the reciprocal of the period (f = 1/T).
If you have a sinusoidal wave function of the form y(x, t) = A sin(kx - ωt + p), the amplitude (A) is the distance between the resting position and the maximum displacement of the wave.
To calculate the frequency, you would measure the time it takes to complete a number of cycles and divide the number of cycles by this time. For instance, if a wave completes 10 cycles in one second, the frequency would be 10 Hz.
