Abstract
The utility model discloses a light phenomenon demonstration instrument comprising a base, a semicircular metal panel and a laser pen bracket. The semicircular metal panel is vertically fixed on the base, scale values are labeled on the metal panel, a glass groove is embedded in the base, a layer of paper plate is pasted and covered on the front face of the semicircular metal panel, and the laser pen bracket is provided with a magnet and can be absorbed on the metal panel. Preferably, the brackets with different heights are symmetrically arranged at both sides of the glass groove for placing different mediums so as to facilitate demonstration of refraction phenomenon of light in the different mediums. By utilizing the light phenomenon demonstration instrument, the refraction and reflection phenomena can be clearly observed, students can conveniently summarize laws of refraction and reflection, the operation is convenient, the error is small, and the light phenomenon demonstration instrument has certain practical value.
Description
Technical field
The utility model relates to a kind of aided education apparatus, specifically a kind of optical phenomenon demonstrator.
Background technology
Existing teaching is simple in structure with the light phenomenon demonstrator, has following shortcoming: 1, because metal decking is reflective, reflection ray can't appear sometimes; 2, laser pen can't be fitted with panel better, and the measurement data error is bigger; 3, can't present direct reflection, diffuse reflection experimental phenomena; 4, can not present the refraction effect of light in material more than three kinds.
The utility model content
The purpose of the utility model provides a kind of simple in structure, the optical phenomenon demonstrator of being convenient to test.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of optical phenomenon demonstrator; Comprise base, semicircle metal decking and laser pen support, vertically fixing semicircle metal decking on base, said metal decking subscript is marked with scale value; Inlay a glass guide channel in the base; Paste a layer paperboard in semicircle metal decking front, said laser pen support is provided with magnet, and is adsorbable on metal decking.
As preferably, said glass guide channel symmetria bilateralis is provided with the support of differing heights, is used to place different media, is convenient to demonstrate the refraction effect of light in different medium.
The beneficial effect of the utility model is:
The utility model can very clearly be observed refraction, reflex, and is convenient to the rule that the student sums up refraction, reflection, and easy to operate, error is little, has certain practical value.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of focussing glass;
Fig. 3 is the structural representation of laser pen support.
Among the figure: 1, semicircle metal decking; 2, cardboard; 3, base; 4, glass guide channel; 5, support; 6, focussing glass; 7, laser pen support; 8, magnet.
Embodiment
A kind of optical phenomenon demonstrator comprises base 3, semicircle metal decking 1 and laser pen support 7, vertically fixing semicircle metal decking 1 on base 3, and semicircle metal decking 1 subscript is marked with scale value, inlays a glass guide channel 4 in the said base 3.
As preferably, paste a layer paperboard 2 in semicircle metal decking 1 front.
Said glass guide channel 4 back are frosted glass, and symmetria bilateralis is provided with the support 5 of differing heights, is used to place different media, the refraction effect of demonstration light in different medium.
During the demonstration refraction effect, can place various media in the glass guide channel 4.When demonstration reflection, direct reflection, diffuse reflection, a focussing glass 6 as on the glass guide channel 4, can be placed different reflectorized materials on focussing glass 6.Laser pen is fixed on the special-purpose laser pen support 7, and said laser pen support 7 is provided with magnet 8, is convenient to during use fit tightly with semicircle metal decking 1, and experimental phenomena is easy to appear.
More than the disclosed specific embodiment that is merely this patent, but this patent is not limited thereto, for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model principle, the distortion of making should be regarded as belonging to the utility model protection domain.
