Investigating the Speed of Water Waves

Examining the velocity profile of the water wave In this experiment we will examine how the wave velocity, wave variations and velocity in the tray are affected. When particles move in the same direction as the direction of the waves, the waves can be longitudinal or the waves can be transverse as the particles move in the direction of 90 °. Even though shear waves can not pass through liquid, water waves are transverse waves. This is because waves travel along the surface of the water.

Each wave travels at a specific speed. Waves of water are unusual because the waves can have different speeds - the speed of the wave depends on how the waves are formed, which is why the tsunami travels much faster than the waves. Unlike water waves, electromagnetic waves always propagate at the same speed (300 million meters per second) and sound waves propagate at the same speed in a particular medium (eg, about 340 meters per second in air). For a wave that is always propagating at the same speed (such as electromagnetic waves), you can calculate the frequency or wavelength using an equation. The high frequency EM wave has a short wavelength and the low frequency EM wave has a long wavelength. For waves with variable speed (such as water waves) you can use equations to calculate speed based on frequency and wavelength

Tsunamis and waves are water waves. As with all waves, they are modes of energy transfer that can be explained by wavelength, velocity, frequency, period, amplitude (height) and energy. As waves, they also show specific ways - they can be reflected, refracted and diffracted, and the two waves can interfere with each other. Shallow is important for tsunami and wave of water. Shallow is an increase in peak height above sea level. This happens when the wave enters a shallow area such as a coastal area. Shallow brought their height and destructive influence to the tsunami. (In the deep sea, the peak of the tsunami is usually one meter below the sea level.) Also, in the shallow area, the waves grow very close to the coast and waves are generated.

Because the wavelength is long, the tsunami looks like a shallow water wave. When the water depth and its wavelength ratio becomes very small, the wave becomes a shallow wave. Shallow water wave movement speed is equal to the square root of the product of gravitational acceleration (9.8 m / s / s) and water depth. Let's see what this means. / S, or over 700 kilometers per hour. Since the speed at which a wave loses its energy is inversely proportional to its wavelength, the tsunami not only propagates at high speed but also extends the distance across the ocean through limited energy loss.
