Here v is the wave speed: ω. v = = f λ. k. (1) ω is the angular frequency, f is frequency, λ is the wavelength and k is the wave number. v is also called phase velocity. A non-dispersive wave has a constant v; dispersion is characterized by a dependence of v on λ. Three different regions are indicated on the dispersion curve from Figure 1:

Figure 8: Ripple generator level Image acquisition To open the data acquisition program, click on the Ripple Tank shortcut located in the quick launch menu. The program will open and ask whether it is OK to launch a camera. If you click Yes, the camera will connect to the computer and will begin streaming the acquisition video.

A progressive wave is an oscillation that travels through matter (or in some cases a vacuum), transferring energy from one place to another, but not transferring any matter. The particles in the matter vibrate as the wave passes through them, but they do not move along with the wave. There are two types of progressive waves.
ψ ( ax − by − vt ) . (1) Here v is the wave speed, and x and y are position coordinates while t is time. The wave speed is in simple cases simply. v = ω = f λ , k where ω is the angular frequency, f is the frequency, is the wavelength, and k is the wave number. The velocity v is technically called the phase velocity.
Oct 27, 2023 · Diffraction round an Edge in a Ripple Tank. Diffraction of water waves after passing an edge. The amount of diffraction depends on the size of the gap compared to the wavelength of the water wave. The diagram below shows how the wavelengths differ with frequency in a ripple tank. The higher the frequency of the motor, the shorter the wavelength.
Oct 1, 2024 · The glass block should sit below the surface of the water and cover only some of the tank floor. The depth of water becomes shallower where the glass block is placed. Since speed depends on depth, the ripples slow down when travelling over the block. The water surface waves slow down when passing from deep to shallow water in the ripple tank.

P5.1 Wave Behaviour. Wave motion can be described in terms of: Wavelength – the distance between a point on one wave and the same point on the next. Typically measured in metres. Amplitude – the distance from equilibrium line to the maximum displacement (crest or trough). Typically measured in metres. Frequency – the number of waves that ...
