Abstract
The utility model discloses an optical refraction demonstration device used for junior middle school physics teaching. The optical refraction demonstration device used for the junior middle school physics teaching comprises a box body and a box cover, laser light sources are arranged at one end in the box body, and a refraction water tank and a lens rack are arranged on the box cover; an optical lens used for replacement is arranged in the convex lens rack, and a demonstration screen is arranged at the other side of the box body and far away from the laser light sources. The optical refraction demonstration device used for the junior middle school physics teaching of the utility model can demonstrate the refraction phenomenon of rays visually via two different light sources, is easy to maintain, is simple in structure and obvious in effect, and has low environment requirements.
Description
Technical field
The utility model relates to a kind of physical teaching aid, particularly relates to a kind of apparatus for demonstrating of light refraction for physics teaching.
Background technology
Light in uniform dielectric along rectilinear propagation.But, likely can be crooked in inhomogeneous Light in Medium, while namely from a kind of medium, inciding another kind of medium, the direction of propagation changes, and this phenomenon is the refraction of light.Must carry out in darkroom carrying out physics teaching geometrical optics experiment, and experimental facilities is bulky, heavy, Portable belt not, can't carry out teaching demonstration by direct Student oriented on classroom.Because only could clearly see light in darkroom, just can observe obvious light path phenomenon, existing optical instrument in experiment, can only complete the reflected light path experiment, and the reversibility of reflected light path, refractive light paths can not be demonstrated out, and required accessory is many, fragile, assembling is regulated loaded down with trivial details, to darkroom, requires high, poor visibility, generally DeGrain.
The utility model content
The purpose of this utility model is to provide a kind of clear directly perceived in order to address the above problem, the light small and exquisite light refraction apparatus for demonstrating that is used for physics teaching.
The utility model is achieved through the following technical solutions:
The utility model comprises casing and case lid, an end in described casing is provided with LASER Light Source, be provided with refraction tank and mirror holder on described case lid, be provided with in described mirror holder and change the optical mirror slip that uses, the opposite side of described casing also is provided with the demonstration screen away from the position of described LASER Light Source.
Further, described LASER Light Source is at least two.
Particularly, two described LASER Light Source are red laser and green (light) laser.
As preferably, the bottom of described casing is provided with aerosol producer.
Further, a side of described casing is transparent plexiglass plate, and opposite side is opaque shadow shield.
The beneficial effects of the utility model are:
The utility model can pass through two Different Light, demonstrates the refraction effect of bright dipping visual in imagely, is easy to safeguard, and is simple in structure, low to environmental requirement, successful.
Description of drawings
Fig. 1 is structural representation of the present utility model;
In figure: the 1-red laser, 2-reflects tank, the 3-optical mirror slip, the 4-case lid, 5-demonstrates screen, 6-mirror holder, 7-aerosol producer, 8-green (light) laser, 9-casing.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments:
As shown in Figure 1, the utility model comprises casing 9 and case lid 4, and the end in casing 9 is provided with LASER Light Source, is provided with refraction tank 2 and mirror holder 6 on case lid 4, be provided with the optical mirror slip 3 that change to use in mirror holder 6, the opposite side of casing 9 also is provided with demonstration screen 5 away from the position of LASER Light Source.
in the present embodiment, LASER Light Source is at least two, two LASER Light Source are red laser 1 and green (light) laser 8, two different LASER Light Source are different by the skew that reflects tank 2 and mirror holder 6 rear generations, can prove out refraction effect thus, the bottom of casing 4 is provided with aerosol producer 7, increase the effect of optical demo, opposite side is opaque shadow shield, casing 4 is generally made six rectangular parallelepipeds, one side of casing 4 is set to sightingpiston with transparent plexiglass plate, opposite side is opaque shadow shield, demonstration screen 5 is selected the hard plastic material to make and is got final product, facilitate the beholder and more intuitively and clearly see the ray trajectory of laser instrument.In use by the liquid that adds different densities and the optical mirror slip 3 of changing different transparencies, adjust different refraction angles, when with red, green two total reflections of bundle laser demonstration light in two groups of light transmission assemblies, transmitting, can see the path of different light rays transmission on demonstration screen 5.
Above embodiment is only unrestricted in order to the technical solution of the utility model to be described.Although with reference to embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, the technical solution of the utility model is modified or is equal to replacement, do not break away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
