Technical field
The utility model relates to a kind of teaching aid, especially a kind of propagation path of light demonstrator.
Background technique
General middle school optical experiment observes the starting point (light source position) that can only see light and terminal (optical screen position in air
Set), it is to be difficult to be scattered light to be observed to obtain, therefore because space of the light between beginning and end is air
The intermediate propagation path poor visibility of Experiments of Optics, experiment effect are very unobvious, for light in intermediate propagation condition, student
Query can be generated, student does not understand obtaining for conclusion very much yet, and experiment only allows student to have an indistinct perception and seemingly to conclusion
Be rather than approval.Traditional Experiments of Optics are more dull, and visual effect is unobvious, while the operability tested is poor,
So that experiment is more empty, student receives the dynamic role of Knowledge Dependency subjectivity, and objective fact illustrates unobvious, can not pass through reality
It tests to excite student to the exploration of optical knowledge full of curiosity, it is brave to be unfavorable for training student in this way for the enthusiasm started, beaten one's brains
In proposition problem, the ability to discover problems and solve them, while enthusiasm, increasing of the excitation to learning physics are improved can not be played
Strong innovative consciousness of students and manipulative ability, the curiosity of Scientific exploration secret.
Utility model content

Dynamic connection hold assembly, the hold assembly are equipped with aerosol producer in the cabinet for connecting at least one point light source.
Using a kind of propagation path of light demonstrator described in the utility model, all point light sources can be along the bracket
Mobile and adjustment incident angle, realizes a variety of Experiments of Optics demands, the strong operability of experiment, while the aerosol producer energy
Enough generate smoke particle object, smoke particle object is stronger to the scattering process of light, can intuitively will by the light in the region into
Row adequately scattering is to be observed, therefore the propagation path of light apparent can be also observed continuously to more intuitive, more shape
As, the propagation path of light demonstrator structure is simple, and it is easy to use, it works well.
Preferably, optical instrument is equipped in the cabinet.
Preferably, the optical instrument is concavees lens.
Preferably, the optical instrument is convex lens.
Preferably, reflection observation board is equipped in the cabinet.
Preferably, each point light source is laser pen.
