Question

I need help with question #2

TWU Physics Laboratory I Oscilloscope it is If an alternating signal is applied to the vertical plates of the oscilloscoe utar This particular possible that a pattern such as that shown in Figure 2 might be obtai wave shape is called a sine wave. The oscilloscops.san voltage by measuring the height of the signal display determined indirectly by determining the width of one cycle and the horizontal s time per unit length. k A be used to determine the pea ed. The frequency Figure 2i Sine Wave obtainud t td LO.k In your experiment, you will be using a digital oscilloscope with a liquid crystal vihal display instead of the analog CRT variety described above. Nevertheless, the oscilloscope's basic purpose is the same: to display a waveform that fluctuates with time. ce Pre-Lab Questions I.
