Optical fiber demonstration instrument, new creative series which used for junior middle school Innovation experimentOptical fiber demonstration instrument
Total reflection of light: the light from the optical density (ie optical refractive index of the medium in this large) medium onto light sparse (ie, the refractive index of light in this medium, small) medium interface, all is reflected back to the original medium the phenomenon.
The socalled optically dense medium and the optical sparse medium is relative. Two substances compared to smaller refractive index, in which the faster the speed of light, just as the optically thinner medium; refractive index of the larger, slower speed of light in which, it is optically denser medium. For example, water, higher refractive index than air, so with the air, the water is the optically denser medium, and the refractive index of glass than water, so that relative to the glass, the water is the optical sparse medium
The device consists of four curved plexiglass rods, LED lights circuit, rotating machine, IC music buzzer, circuit switching, base composition.
Dimensions: 350mm × 260mm × 324mm; base using a common PVC molding, base size: 350mm × 260mm × 70mm; 10mm high legs using special rubber pads to prevent vibration and slipping.
Power supply 220VAC.
