The utility model discloses convenient to use, simple structure, can verify light along the reflection law of straight line propagation, deflection and light, verification method is simple, can let the more deep law of understanding these light of classmates.
Description
Technical field
This utility model relates to a kind of optical teaching aid, and specifically a kind of light propagates demonstration device.
Background technology
In curricula, relate to the various rules telling about light, but the understanding of student is strengthened in the teaching aid demonstration lacking a kind of performance directly perceived, classmates can only be allowed to understand by the uninteresting imagination, not reach preferable teaching efficiency.
Utility model content
The purpose of this utility model is to provide a kind of light to propagate demonstration device, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of light propagates demonstration device, including illuminator, half Circular glass, ruler, generating laser, swivel head, the first rotating shaft, projection and the second rotating shaft；Described illuminator is a rectangle glass minute surface, is embedded at the diametrical position of half Circular glass；Described half Circular glass is semicircle safety glass, is fixed on ruler by the first rotating shaft；Described ruler is made of plastics；Described generating laser is embedded on swivel head；Described swivel head is connected on ruler by the second rotating shaft, and swivel head is provided with projection；Described projection is provided with a pair；Described first rotating shaft connects half Circular glass and ruler.
As further program of the utility model: be carved with angle index line on described half Circular glass.
As further program of the utility model: be carved with the graduation mark that unit is millimeter on described ruler.
As this utility model further scheme: the thickness of described half Circular glass is less than the thickness of ruler.
Compared with prior art, the beneficial effects of the utility model are:
This utility model is easy to use, simple in construction；Can verify that light linearly propagate, the refraction of light and the reflection law of light, verification method is simple, can allow the law understanding these light that classmates are more deep.

In figure: 1-illuminator, 2-half Circular glass, 3-ruler, 4-generating laser, 5-swivel head, 6-the first rotating shaft, 7-projection, 8-the second rotating shaft.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
Referring to Fig. 1-3, a kind of light propagates demonstration device, including illuminator 1, half Circular glass 2, ruler 3, generating laser 4, swivel head the 5, first rotating shaft 6, projection 7 and the second rotating shaft 8；Described illuminator 1 is a rectangle glass minute surface, is embedded at the diametrical position of half Circular glass 2, is used for reflecting light；Described half Circular glass 2 is semicircle safety glass, is fixed on ruler 3 by the first rotating shaft 6, and is carved with angle index line on half Circular glass 2；Described ruler 3 is made of plastics, and is carved with the graduation mark that unit is millimeter, linearly propagates for picture straight line and checking light；Described generating laser 4 is embedded on swivel head 5；Described swivel head 5 is connected on ruler 3 by the second rotating shaft 8, and swivel head 5 is provided with projection 7；Described projection 7 is provided with a pair, postrotational fixing for swivel head 5；Described first rotating shaft 6 is for connecting half Circular glass 2 and ruler 3, and the thickness of half Circular glass 2 is less than the thickness of ruler 3.
Operation principle of the present utility model is: open generating laser 4, by observing the laser beam straightline propagation of verifying light the most parallel with ruler 3 that generating laser 4 sends；By a part for ruler 3 being inserted in water, laser beam part in water be can be observed not parallel with ruler 3, then light there occurs refraction effect；By rotating swivel head 5, being rotated to by generating laser 4 with on the position of initial phase pair, rotating semicircular glass 2, there is reflex by inlaying illuminator 1 therein, and can verify that angle of incidence is equal to angle of reflection according to the angle index line on half Circular glass 2 in light.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art is possessed, it is also possible to make a variety of changes on the premise of without departing from this patent objective.
