I think the figure is misleading - the wave ought to be drawn about
twice as high (i.e. about 16 times the height of the person on the
sidewalk on the left side of the picture). Of course, the picture was
taken with a short focal length lens, with pretty dramatic
perspective. Does the figure imply that the corner tower on that
building is 30 m high? I doubt that. Using the author's own
conversion factor, 30 m = 10 storey building, and that corner tower is
surely not 10 storeys high.
