On the grid in the Show Your Work space, draw one complete cycle of the wave.
A wave traveling through a uniform medium has an amplitude of 0.20 meter, a wavelength of 0.40 meter, and a frequency of 10. hertz.

a) Mark an appropriate scale on the axis labeled “Current (A).”
b) Plot the data points for current versus potential difference.
c) Draw the line or curve of best fit.
