In physics, a ripple tank is a shallow glass tank of water used to demonstrate the basic properties of waves. It is a specialized form of a wave tank. The ripple tank is usually illuminated from above, so that the light shines through the water. Some small ripple tanks fit onto the top of an overhead projector, i.e
A wave tank is a laboratory setup for observing the behavior of surface waves. The typical wave tank is a box filled with liquid, usually water, leaving open or air-filled space on top. At one end of the tank, an actuator generates waves; the other end usually has a wave-absorbing surface. [1] A similar device is the ripple tank, which is flat ...
The first wave research equipment was the wave flume. [3] It is 360 feet (110 m) long, 12 feet (3.7 m) wide, and 15 feet (4.6 m) deep. [3] It is used to simulate the waves of the ocean, and creates 5-foot-high (1.5 m) waves with currents strong enough to surf on. [3] The wave flume holds up to 350,000 gallons of water. [3]
Shallow-water equations can be used to model Rossby and Kelvin waves in the atmosphere, rivers, lakes and oceans as well as gravity waves in a smaller domain (e.g. surface waves in a bath). In order for shallow-water equations to be valid, the wavelength of the phenomenon they are supposed to model has to be much larger than the depth of the ...
According to Scott, this is the last 1970s tank-driving simulator left in the world. The unit features a box in which users can sit with realistic controls that would be found inside the cockpit ...
Thomas Young's sketch of two-slit diffraction for water ripple tank from his 1807 Lectures [6]: 139 . The effects of diffraction of light were first carefully observed and characterized by Francesco Maria Grimaldi, who also coined the term diffraction, from the Latin diffringere, 'to break into pieces', referring to light breaking up into different directions. [7]
Since this was a networked simulation, each simulation station needed its own display of the shared virtual environment. The display stations themselves were mock-ups of certain tank and aircraft control simulators, and they were configured to simulate conditions within the actual combat vehicle. The tank simulators, for example, could ...
The mathematical discussion presented above does not require quantum mechanics at its heart. In particular, the derivation is essentially valid for waves of any sort. With slight modifications to account for the squaring of amplitudes, the derivation could be applied to, for example, sound waves or water waves in a ripple tank.
