Abstract
The present invention provides a light path display combination, especially a device of showing light path. The device belongs to the teaching laboratory equipment, characterized in that it is composed of a display board and a demonstration frame, when beam passes the display board composed by reflecting powder and transparent solid, the light path is shown, directly showing the straight propagation, reflection and refraction discipline of light, it is convenient for laboratory observation.
Description
Technical field
The present invention relates to a kind of light path and show combination, the device that especially a kind of route that light is passed through shows.Belong to teaching experimental equipment.
Background technology
In the course teaching of middle school " science ", some physioptial content: the rectilinear propagation of light, reflection of light law and refraction law, this part teaching is when running into the demonstration light path, because light all is visible hardly by transparent bodies such as empty G﹠Ws, can't show the route that bright dipping is passed through, so teaching there is not intuitive, the student is to the understanding of this part lack of knowledge perception.Also the someone attempts making some backgrounds and is used to set off light at present, but always is difficult to get a desired effect.
Summary of the invention
The object of the present invention is to provide a kind of device that in the light path teaching, can show light path convenient, intuitively.
The present invention realizes like this.Immiscible reflective powder is mixed with transparency liquid, allow reflective powder be evenly distributed in and be frozen into a transparent display board in the liquid, when then light beam is by this display panels, reflective powder just can be with light to all directions diffuse reflection, thereby can show the route that bright dipping is passed through when making light pass through this piece transparent panel.When being placed on display board on the corresponding reflection demonstration frame that the protractor background is arranged, allow light inject this display panels and the mirror reflects by the bottom goes out reflection ray from different angles, can clearly see incident ray and reflection ray like this, make the student see that intuitively incident angle and reflection angle equate, thereby grasp reflection law; Equally, two different display boards of refractive index are stacked together, allow light from wherein one inject, through the interface of stack, just can see incident ray and refracted ray intuitively and sum up the relation of angle.

Number in the figure is followed successively by: demonstration frame background 1, and level crossing 2, at the bottom of the demonstration frame 3, display board 4, light source 5.
Embodiment
Referring to Fig. 1, (as high temperature) under given conditions chooses the liquid that good transparency also can be formed transparent solid at normal temperatures, as the liquid down pmma material of high temperature; Choose the reflective powder that is insoluble to this liquid, reflective powder is made by the material with good catoptrical characteristic, enough carefully the dust-size that hikes up during letter written with chalk on erasing the board in seeming most to impart knowledge to students.Reflective powder is mixed with transparency liquid, allow reflective powder be evenly distributed in and be frozen into a transparent display board 4 in the liquid, reflective powder amount is wanted appropriateness, too much can obstruct the light, and influences penetrability, and the light that reflects very little is just few, influences the brightness of light.
Referring to Fig. 2, reflection demonstration frame 3 is formed at the bottom of by frame background 1 and frame, in order to lay the display board 4 of demonstrating reflex time, is provided with a facet mirror 2 at the bottom of the frame, and level crossing 2 is with equal at the bottom of the frame, and the frame background is decorated with protractor and makes background, the angle of passing through in order to measuring light.The demonstration frame can be made appearance shown in Figure 2 with plastics class material, and size is corresponding with display board, follows the size of plate 4 according to the show to determine the size of frame, can become the form of Fig. 4 to get final product when making display board 4 be placed into frame.
Referring to Fig. 3, refraction demonstration frame is also by 3 forming at the bottom of frame background 1 and the frame, with shown in Figure 2 different is, the height of background frame is wanted can hold to stack two display panels, background be depicted as two relative protractors, do not adorn level crossing at the bottom of the frame, can become the form of Fig. 5 to get final product when making two display panels put into frame.
Referring to Fig. 4, put into the example that frame is demonstrated in reflection for display board 4, constitute the teaching aid of light reflection lecture experiment.
Referring to Fig. 5, be the example that the different display board of two refractive indexes 4 is put into refraction demonstration frame, constitute the teaching aid of anaclasis lecture experiment.
Referring to Fig. 6, be the example of " the rectilinear propagation teaching of light ", the light that allows light source 5 penetrate is injected display board 4, and then light by the reflective powder reflection in the transparent panel, shows light path by display board, and the thick black line among the figure is promptly represented the light path that manifests.
Referring to Fig. 7, example for " reflection of light " teaching, the light that allows light source 5 penetrate is injected display board 4, and the central authorities of alignment box baseplane mirror 2, then incident ray and reflection ray manifest in display board, then can measure incident angle and reflection angle by the protractor background in the background frame 1, draw the relation of incident angle and reflection angle, the incident angle that conversion is different can be demonstrated the reflection of light rule repeatedly, makes the student observe the reflection of light phenomenon very intuitively.
Referring to Fig. 8, refraction teaching example for light, the light that allows light source 5 penetrate is injected top display board, and aims at the mid point of background protractor, because two display panels refractive index difference, then incident ray is in the refraction of generation at the interface of mid point, protractor by background then can measure incident angle and refraction angle, draws the relation at incident angle and refraction angle, the incident angle that conversion is different, can demonstrate the law of refraction of light repeatedly, make the student observe the refraction effect of light very intuitively.
Claims (2)
1, a kind of light path shows combination, especially a kind of device that can represent light path.It is characterized in that forming,, represent rectilinear propagation, reflection of light and the law of refraction of light intuitively, be used for the observation experiment of light path when light beam can show light path during by display board by showing not plate, demonstration frame.
2, light path as claimed in claim 1 shows combination, it is characterized in that display board is made up of the reflective powder and the transparent solid that are evenly distributed
