The oscillation period *T* (in seconds) for the bubble effect varies as the cube root of the energy *E* and inversely as the 5/6th power of the pressure. The relation is

*T*=0.450

*E*

^{1/3}/(

*D*+33)

^{5/6}or

*T*=0.108

*E*

^{1/3}/(

*D*′+10)

^{5/6},

where *E* is the energy in joules, *D* is the depth in feet, and *D*′ is the depth in meters. See Figure R-5.
