I had the same impression as 24.60.117.113. So, either the flames are higher at both the nodes and anti-nodes (as the first few sentences of this section would indicate), or the graphic is wrong. If the graphic is correct, the nodes and anti-nodes should be labeled.
Furthermore, it is not clear what the "648 mm" is measuring. -- Phyzome is Tim McCormack 00:59, 23 December 2007 (UTC)
