David,

It seems to be reflections from the surface (or any other reflective surfac=
e) would be antiphase only at certain frequencies for a given distance, or =
at certain distances for any given frequency and cannot accurately be descr=
ibed simply as 'in antiphase'. Moreover, given the speed of sound in water =
is roughly four times faster than the speed in air, the wavelengths would b=
e roughly a quarter as long, not four times as long.
