2. Motion aftereffect - Wikipedia

   en.wikipedia.org/wiki/Motion_aftereffect

   The motion aftereffect is believed to be the result of motion adaptation. For example, if one looks at a waterfall for about a minute and then looks at the stationary rocks at the side of the waterfall, these rocks appear to be moving upwards slightly. The illusory upwards movement is the motion aftereffect.

3. Brownian noise - Wikipedia

   en.wikipedia.org/wiki/Brownian_noise

   The sound is a low roar resembling a waterfall or heavy rainfall. See also violet noise, which is a 6 dB increase per octave. Strictly, Brownian motion has a Gaussian probability distribution, but "red noise" could apply to any signal with the 1/f 2 frequency spectrum.

   Slow motion video of a fruit falling into water. In fluid mechanics, a splash is a sudden disturbance to the otherwise quiescent free surface of a liquid (usually water).The disturbance is typically caused by a solid object suddenly hitting the surface, although splashes can occur in which moving liquid supplies the energy.

6. Illusions of self-motion - Wikipedia

   en.wikipedia.org/wiki/Illusions_of_self-motion

   When a large part of the visual field moves, viewers feel like they have moved and that the world is stationary. [4] For example, when one is in a train at a station, and a nearby train moves, one can have the illusion that one's own train has moved in the opposite direction.

   A waterfall is generally defined as a point in a river where water flows over a steep drop that is close to or directly vertical. In 2000 Mabin specified that "The horizontal distance between the positions of the lip and plunge pool should be no more than c 25% of the waterfall height."

   Other types of transducers include variable-reluctance (or moving-armature, or electromagnetic) transducers, where magnetic force acts on the surfaces of gaps, and moving coil (or electrodynamic) transducers, similar to conventional speakers; the latter are used in underwater sound calibration, due to their very low resonance frequencies and ...
