Description
Technical field
The utility model relates to a kind of teaching aid, particularly a kind of Middle School Physics optical demonstration instrument.
Background technology
Teaching aid can help student to understand knowledge better, optics is very important learning content in Middle School Physics, wherein, light is linearly propagated, the reflection of the refraction of light and light is difficult to allow student understand by oral English teaching merely, by real teaching aid come lecture experiment more visual pattern easily understand, the simple teaching aid above-mentioned functions not integrated in the market.
Summary of the invention
For making up the deficiencies in the prior art, the utility model provides a kind of structure simple, Middle School Physics optical demonstration instrument easy to use.
The utility model is achieved by the following technical solution:
A kind of Middle School Physics optical demonstration instrument, comprise display board, its special character is: described display board is arranged on support bar, and support bar is connected with base rotation; Described display board centre position is provided with circular angle dial, and the latter half of this angle dial is provided with semi-circle shaped transparent glass blocks, the surface level of clear glass block is placed with movable smooth mirror surface; The surrounding of described angle dial is fixed with ring ring, and this ring ring is provided with slidably LASER Light Source.
Middle School Physics optical demonstration instrument of the present utility model, described support bar is made up of several sections of can stretch up and down.
The beneficial effects of the utility model are: the utility model structure is simple, can the demonstration optical phenomena of image, help student to sharpen understanding optical knowledge.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing 1 is structural representation of the present utility model.
In figure, 1 display board, 2 support bars, 3 bases, 4 index dials, 5 glass blocks, 6 ring rings, 7 LASER Light Source, 8 smooth mirror surfaces.
Embodiment
Accompanying drawing is a kind of embodiment of the present utility model.This embodiment comprises display board 1, and display board 1 is arranged on support bar 2, and support bar 2 is made up of several sections of can stretch up and down, and support bar 2 and base 3 are rotationally connected; Display board 1 centre position is provided with circular angle dial 4, and the latter half of this angle dial 4 is provided with semi-circle shaped transparent glass blocks 5, the surface level of clear glass block 5 is placed with movable smooth mirror surface 8; The surrounding of angle dial 4 is fixed with ring ring 6, and this ring ring 6 is provided with slidably LASER Light Source 7.
Smooth mirror surface 8 is light tight, when LASER Light Source 7 sends in illumination to smooth mirror surface 8, light reflects, and incident ray and reflected ray are presented on display board 2, can read incident angle and reflection angle from angle dial 4, take away smooth mirror surface 8, clear glass block 5 is organic glass, and LASER Light Source 7 shines clear glass block 5 and reflects, and incident ray and refracted ray are presented on display board 2, incident angle and refraction angle can be read, the display optics feature of image from angle dial 4.Support bar 2 can stretch up and down, and regulate height during use as required, support bar 2 can rotate on the base 3, can meet the student being sitting in diverse location and see experimental demonstration clearly.
