Time and Voltage
19
The vertical axis measures voltage. The distance along one small
square represents 0.1 mV, and along one large square, 0.5 mV.
You will need to memorize these numbers at some point, so you
might as well do it now.

Both waves are one large square in duration (0.2 seconds), but the
second wave is twice the voltage of the first (1 mV compared with 0.5
mV). The flat segment connecting the two waves is five large squares
(5 × 0.2 seconds = 1 second) in duration.
