Abstract
The utility model relates to a reflection law demonstrator and belongs to the technical field of teaching tools. The reflection law demonstrator provided by the utility model is simple in structure and convenient in operation. The reflection law demonstrator comprises a rectangular base plate, a semi-circular rear plate and an arc-shaped top plate corresponding to the rear plate. A structure of the reflection law demonstrator is characterized in that an edge of the rear plate has a scale, the scale uniformly divides semi-circumference of the rear plate, one side of the top plate has a gap, a connection position of the base plate and a circle center of the rear plate has a flat mirror, and a lower portion of the base plate has a support.
Description
Technical field
The utility model is divided by International Patent Classification (IPC) (IPC) and is belonged to physical piece, education; Cryptology; Show; Advertisement; Big type of seal, education or demonstration equipment; Be used to the apparatus of imparting knowledge to students or communicating by letter with blind person, deaf person or mute; Model; Planetarium; Terrestrial globe; Map; The figure watch group, the model that science, medical science or mathematics are used, the device technique field that for example is used to demonstrate with full-size(d), more specifically saying so relates to a kind of reflection of light law demonstration device.
Background technology
The reflection of light law is the important content of opticator in the physics, also is the basis of studying other complicated knowledge in depth.
The reflection of light law is: reflection ray and incident ray, normal are at grade; Reflection ray and incident ray separation are in the both sides of normal; Reflection angle equals incident angle.The reflection of light law can reduce: " two jiaos equate for three-way coplane, the separation of two lines ".The reflection of light law is proposed by the French civil engineering work physicist's Fresnel (1788～1827) of holding concurrently, and he has found the relation between reflection/refraction and the viewpoint angle, and therefore, reflection of light is called Fresnel reflection again.
Because the reflection of light law is that learn on the basis with the physical phenomenon, the teaching aid that therefore in teaching, needs demonstration comes aided education, to strengthen the Students'learning effect.
Summary of the invention
The utility model is exactly to the problems referred to above, and a kind of reflection of light law demonstration device simple in structure, easy to use is provided.
In order to realize the above-mentioned purpose of the utility model; The utility model adopts following technical scheme; The utility model comprise rectangular base plate, semicircular back plate and with the corresponding circular arc top board of back plate, the edge of plate has scale after its structural feature, the semi-circumference five equilibrium that scale will the back plate; One side of top board has the slit, has level crossing on the position that links to each other with the plate center of circle, back on the base plate, and floor below has support.
As a kind of preferred version, top board has black paint towards a side surface of base plate, and back plate surface has white paint.
The beneficial effect of the utility model:
(1) simple in structure
The utility model comprise rectangular base plate, semicircular back plate and with the corresponding circular arc top board of back plate, the edge of back plate has scale, scale is the semi-circumference five equilibrium of plate afterwards; One side of top board has the slit, has level crossing on the position that links to each other with the plate center of circle, back on the base plate, and floor below has support; Do not use too much member, structure is very simple.
(2) easy to use
The utility model with the source alignment slit, makes irradiate light to level crossing in use, can see the light of reflection on the plate in the back, can compare the size of incident angle and reflection angle through scale, and is very easy to use.
Description of drawings
Fig. 1 is the structural representation of the utility model.
In the accompanying drawing, 1 is support, and 2 is base plate, and 3 is level crossing, and 4 is the back plate, and 5 is the slit, and 6 is scale, and 7 is top board.
Embodiment
Clearer for technical matters, technical scheme and beneficial effect that the utility model is solved, below in conjunction with accompanying drawing and embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The utility model comprise rectangular base plate 2, semicircular back plate 4 and with back plate 4 corresponding circular arc top boards 7, the edge of back plate 4 has scale 6, scale 6 generals are the semi-circumference five equilibrium of plates 4 afterwards; One side of top board 7 has slit 5, has level crossing 3 on the position that links to each other with plate 4 centers of circle, back on the base plate 2, and base plate 2 belows have support 1.
As a kind of preferred version, top board 7 has black paint towards a side surface of base plate 2, and back plate 4 surfaces have white paint.
Black paint can absorb light, prevents that reflection ray from being fired back, and white paint can make obvious, the observation easily of reflecting effect.
Be with being appreciated that; More than about the specific descriptions of the utility model; Only be used to the utility model is described and be not to be subject to the described technical scheme of the utility model embodiment; Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model, to reach identical technique effect; As long as satisfy the use needs, all within the protection domain of the utility model.
