    1. To represent the wave graphically, plot distance on the x-axis and density on the y-axis with a central dashed line for average density. Draw a periodic sine curve where the crest reaches 3 units above average density and the trough falls 3 units below. The horizontal distance from one crest to the next consecutive crest must measure exactly 4 cm.
