The figure below is an oscilloscope trace of a sine wave. The horizontal axis represents time and the vertical axis represents voltage. The time/division is set to 1 ms, which means each major horizontal division is 1 millisecond. Note that each major division is divided into 5 minor divisions. The volts/division is set to 50 mV, meaning each major vertical division is 50 mV. So one square is 1 ms x 50 mV.
a) Estimate the period of the wave in ms.
b) Estimate the period of the wave in seconds.
c) Estimate the frequency of the wave in Hz.
d) If the time/division was changed to 2 ms, will there be more, fewer, or the same number of complete waves shown on the screen?
e) Estimate the amplitude of the wave in mV.
