  • $\begingroup$ The wave idea is interesting. But first there has to be something creating the wave, something she already has had experience with, and knows how high and fast the wave should be. Normally, in such training, there is no reason to 'make waves'. In fact, I suspect it would be discouraged. Light ripples reflecting on the bottom of the tank from the surface waves, perhaps, like in a ripple tank? Will the wave travel 'shadow' be slower or faster moving along the bottom? This has possibilities. $\endgroup$ Commented Apr 6, 2021 at 14:55
  • $\begingroup$ Every move the trainee (or divers) make will create waves and ripples on the water surface. Even if not consciously noticed, the (to the trainee) sudden change in the character of the waves, their shadows and refraction will be instantly noticed as "something changed." Safety sense will then result in a careful check around, likely in talking to "mission control" as well. $\endgroup$ Commented Apr 6, 2021 at 15:03

    $\begingroup$ So, do the wave ripple shadows propagate slower or faster? I agree with the 'back of the mind' safety consciousness thing. They are trained to not disregard 'intuition', but they are trained to manage it to prevent paranoia. $\endgroup$ Commented Apr 6, 2021 at 15:11

    $\begingroup$ The waves themselves propagate slower under lower gravity. The same amount of energy lifts the water higher, and it falls back more slowly. $\endgroup$ Commented Apr 6, 2021 at 15:47
  • $\begingroup$ That part I understand. The height would be the wave 'amplitude' and the rate of the rising and falling determines the 'frequency'. But does frequency translate into wave speed? One blip per second and ten blips per second can still propagate at the same speed in a ripple tank. I suppose the waves would be higher amplitude, lower frequency, longer wavelength, and that would appear that they are traveling slower. Like the speed of the record was slowed way down and volume was turned up.
