Abstract

An instrument for demonstrating transverse waves and standing waves in different media is characterized in that different liquids are added into a medium box, one end of a rope is fixed at one end of a crank, a motor rotates to drive a main shaft to rotate, the main shaft drives a crankshaft to rotate, the crank vibrates up and down along with the crankshaft, the length of the rope is adjusted, and the other end of the rope is fixed. When the length of the rope reaches a proper length, a standing wave phenomenon can be generated on the rope, the phenomenon of transverse waves can be seen from the water surface through the upper part and the lower part of the crank in the other medium box, or the difference of waves under different media can be seen through placing different media in each medium box.

Description

technical field [0001] The invention belongs to the technical field of experimental devices and relates to demonstration of physical phenomena, in particular to a demonstration instrument for transverse waves and standing waves in different media. Background technique [0002] The characteristic of the transverse wave is that the vibration direction of the particle is perpendicular to the propagation direction of the wave, and the standing wave is a vibration phenomenon formed by the superposition of two special waves. However, there is no related equipment to embody waves in different media. Contents of the invention [0003] The object of the present invention is a demonstration instrument for transverse waves and standing waves in different media. In this device, different media can be placed in the media box to demonstrate the propagation characteristics of waves in different media. [0004] In order to achieve the above object, the technical scheme adopted in the pre...
