The horizontal axis on the top plots position on the transmission line between z equals 0 and z equals l, marking l over 4, l over 2, and 3 l over 4 in between. Two vertical axes on the left and right pointing downwards plot time t. The graph shows straight line segments that zigzag between the two vertical axes while moving down gradually, indicating progress of the voltage wave bouncing back and forth on a transmission line. The top of the bounce diagram indicates reflection coefficients as gamma equals gamma sub g at the generator end on the left, and gamma equals gamma sub L at the load end on the right.

Five straight line segments are shown in the bounce diagram. The voltage is V sub 1 plus between 0 and T. It bounces back to gamma sub L times V sub 1 plus between T and 2 T. It moves further to gamma sub g times gamma sub L times V sub 1 plus between 2 T and 3 T, and bounces back to gamma sub g times gamma sub L squared times V sub 1-plus between 3 T and 4 T. The last segment shows voltage of gamma sub g-squared times gamma sub L-squared times V sub 1-plus between 4 T and 5 T before bouncing back.

A vertical dashed line is drawn at z equals l over 4 up to t equals 4 T to measure the voltage V at (l over 4, 4 T).
