Complete Wave Motion Demonstrator
Impressive Wave Demonstration That Your Whole Class Can See
Based on research done at Bell Laboratories, the design of this multiple rod demonstrator allows all the fundamental aspects of wave theory to be shown in an effective manner. You can use this high-quality apparatus to investigate the behavior of mechanical and electromagnetic waves. You can also use the demonstrator's three sections together or separately to illustrate the principles of wave propagation, reflection, and transmission-or for exploring interference, resonance, and standing wave phenomena. Each of the demonstrator's three sections consists of a large A-frame base with an array of steel bars attached to it with equally spaced pivots and longitudinal torsion spring. Two of the sections are 92cm in length and the third section is 60cm long. The bars on one of the 92m sections are 46cm long, giving a "slow" wave propagation velocity. The other wave section has 23cm bars for "fast" wave velocity only. The third and shorter section operates like an impedance matching transformer because its bars taper exponentially from 46cm to 23cm. All the bars have yellow tips to let you view them from he side. The base folds flat for easy storage. Includes clamp for rigid termination, dash pot for damping reflections, two couplers for connecting the sections and complete instruction manual. Also available separately is the Slow Section for small scalev demonstrations. Includes terminator clamp, dust post and manual.
波動示範器
此儀器由許多的細棒所組成,這是一個有趣的裝置可示範波動的現像。
此高品質的實驗器材可用來觀察機械波及電磁波。你也可以將此裝置
的三個部分分開或一起使用來觀察波的傳播.反射.穿透,甚至干涉.共振
.駐波的現像。此裝置的三個部分都由一A形底座及一整排的鋼棒等間
距的裝置在上面,其中兩部分長 92公分,另一部分長 60公分。前兩部分
上的鋼棒長 46公分,提供波速較慢的進行波。另一部分的鋼棒長 23公
分,提供波速較快的進行波。第三較短的部分就像是一個阻抗。全部的。
鋼棒上貼有黃色的小紙條讓你從旁邊也可以看的很清楚。底座可以折
疊使覺好放置。
