Quizplus · Accepted Answer

The frequency of a waveform is the inverse of its period. In the given scenario, if the Time-per-division setting is 1.0 ms/Div and assuming Waveform A completes one cycle in 2.5 divisions (as an example, since the actual divisions are not specified), the period of Waveform A would be 2.5 ms (2.5 divisions * 1.0 ms/Div). The frequency is the inverse of the period, so $f = \frac{1}{T} = \frac{1}{2.5 \times 10^{-3}} = 400 \, \text{Hz}$.
