The image is a graph titled "Waveform B." The x-axis represents time in seconds (s), ranging from 0 to just over 0.01 seconds. The y-axis represents amplitude, with values ranging from -1 to 1.

The waveform depicted on the graph shows an oscillating pattern that resembles a sine wave. It starts at zero and rises to a positive peak of approximately +0.5 before falling back down to zero. Then it dips below the x-axis to a negative value around -0.5, before rising again towards zero but not quite reaching it.

There are no people or characters in this image; it is purely a graphical representation of an electrical signal over time. The graph uses a grid for reference and clarity, with dotted lines marking intervals on both axes.
