Description

{MULTI WAVEMOTION EXPERIMENTAL SYSTEM}

The present invention relates to a multi-wave experiment system, and more particularly, to a multi-wave experiment system capable of simultaneously testing a standing wave, a wave wave, and a Clonoid figure associated with a wave.

'Wave' means that the shaking (vibration) of the material from one place spreads to another place. There are various types of waves and wave phenomena. Typical types are standing waves, water waves, and a Chladni pattern. 'Standing wave' refers to a wave that oscillates in place when two waves with the same frequency (amplitude) and the same vibration move in opposite directions and do not advance in any direction when overlapping. The point that does not vibrate at all in the standing wave is called the node and the part that oscillates at the maximum amplitude is called the double. 'Wave wave' refers to the fluctuation of the water that is propagated to the four sides by the water. If more than one wave occurs at the surface, 'interference' or 'superposition' occurs between waves. There are 'constructive interference' and 'destructive interference' in wave interference, and constructive interference of wave is a phenomenon in which wave propagates in the opposite direction and overlaps in the middle, which means that the water surface rises to the combined height of wave bundles , The wave cancellation of wave waves is a wave phenomenon in which the traveling direction and the phase are inverted by 180 degrees, facing each other. This interference phenomenon is canceled when the two are overlapped and overlapped. In addition, 'Clanny figure' was discovered by Ernst Cladni, a 19th century German musician. It refers to a pattern created by vibrating sound according to frequency using the vibration generated by sound energy. That is, when the energy of sound is transmitted to the waves, the sand on the metal plate produces different patterns depending on the frequency, which is called the Claudian shape. The Claudian figure is also a type of standing wave and is used to test the quality of string instruments such as violins and cellos.

Currently, middle school curriculum and high school curriculum students are learning about the wave and wave phenomena described above. In order to test these wave and wave phenomena, expensive experimental devices exist. For example, there are a standing wave experiment device using a function generator and an amplifier, a wave wave experiment device using a function generator and an amplifier, and a Claudny figure experiment device using a function generator and an amplifier. However, (At least 800,000 won to several million won), and only one wave and wave phenomenon can be observed in one experimental apparatus. Therefore, when the students learn about the wave and wave phenomena as described above, only the theoretical class is practiced. Since waves and wave phenomena can not be easily identified in the real world, there is a problem that it is not easy for students to understand the principle of wave and wave phenomena when studying them only theoretically.
