Abstract
The utility model discloses a experimental facility for reflection law of light, which is capable of catching sight of rays and reflecting the reflection law content of light vividly, and is composed of a base (1), an outer casing (2), a left optical screen (11) and a right optical screen (12), wherein a lens (7) is arranged on the base (1), a smoke hole (9) is arranged on a front side board of the outer casing (2), the left optical screen (11) is movably connected with the right optical screen (12), the right optical screen (12) is fixed on the lens (7), a gap is arranged at the right lower corner of the left optical screen (11), a dragging rod (10) is fixed on the left optical screen (11), a magnetic stripe board (4) is arranged inside the right optical screen (12), and a laser pen (3) is adsorbed onto the magnetic strip board (4). The utility model is mainly applied to teaching the reflection law of light to students in schools.
Description
Technical field
The utility model relates to a kind of smooth reflection law experimental provision.
Background technology
At present, in the teaching of reflection of light law, existing smooth its light source of reflection law demonstration device is to use hand-guided, the student is difficult to see simultaneously incident ray and reflection ray, its optical screen plate is that a straight plate can not prove reflection ray and incident ray visually on same plane, and it is not dark to make the student be difficult for understanding memory, and the student can't see the round of light in the air when doing experiment, tend to think that reflection ray disappears, thereby form wrong understanding.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of smooth reflection law experimental provision is provided, it can control light source easily, see incident light and reflected light very easily simultaneously, can prove visually that reflection ray and incident ray are on same plane, easy to understand increases student's memory, the student can see the round of light when doing experiment, avoided wrong cognition.
For solving the problems of the technologies described above, the utility model is made up of base, shell, left optical screen plate and right optical screen plate, on base, be provided with eyeglass, be provided with the smog hole on the front side board of shell, for flexibly connecting, right optical screen plate is fixed on the eyeglass between left optical screen plate and the right optical screen plate, the lower right corner of left side optical screen plate is provided with breach, pull lever is fixed on the left optical screen plate, right optical screen plate be provided with the magnetic stripe plate inside, laser pen adsorbs on it.
Owing to adopt technique scheme, the student who uses the utility model to do experiment observes incident ray and reflection ray very easily simultaneously, can prove the reflection of light law visually, meanwhile the student can see the round of light in the air, helps correct understanding and remembers the reflection of light law deeply.
Description of drawings
Fig. 1 is the utility model structural representation; Fig. 2 is the left view of Fig. 1.
Among the figure: end Cuo 1, shell 2, laser pen 3, magnet 4, hinge 5, angle groove 6, eyeglass 7, breach 8, smog hole 9, pull lever 10, left optical screen plate 11, right optical screen plate 12.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
The utility model shown in Figure 1 is by base 1, shell 2, left side optical screen plate 11 and right optical screen plate 12 are formed, base 1 is that thick approximately 2 centimeters plastic plate is made, groove is arranged one around rectangular, shell 2 is detained within it, be stained with an eyeglass 7 above the base 1, left side optical screen plate 11 is connected with right optical screen plate 12 usefulness hinges 5, the two also is made of plastic, right optical screen plate 12 internal magnets 4 cast in the plastics, the bottom surface of right optical screen plate 12 is fixed on the eyeglass 7 with glue, for laser pen 3 can be held by magnet 4, wrapped up one deck iron sheet in the outside of laser pen 3, in order to show the multiple angles of laser pen 3 irradiations or reflection, a left side, right optical screen plate 11, be shaped on angle groove 6 on 12, smog hole 9 is arranged on the front side board of shell 2, and the lower right corner of left optical screen plate 11 is provided with a breach 8.
One end of pull lever 10 shown in Figure 2 cements in the back side of left optical screen plate 11, and its length passes the back side panel of shell 2.
Shell 2 usefulness glass of the present utility model stick together and make, and also can make of other transparent material.
Use the utility model, the power supply opening of laser pen 3 is adsorbed on the selected angle position of right optical screen plate 12 with it, shell 2 is buckled on the base 1, put into an amount of smog from smog hole 9, adjust the angle of left optical screen plate 11 and right optical screen plate 12 by pull lever 10, work as a left side, right optical screen plate 11,12 on a vertical plane promptly 180 ° the time, the incident light that is sent by laser pen 3 will appear on the right optical screen plate 12, reflex on the left optical screen plate 11 by eyeglass 7 again, when left optical screen plate 11 and right optical screen plate 12 not on a vertical plane, reflected light can not occur when promptly being greater than or less than 180 °, if angle will see through the back side that breach 8 appears at left optical screen plate 11 less than 180 ° of reflected light, owing to have smog incident light and catoptrical light to see in the shell 2, so more help study, understand, the memory reflection law.
Claims (3)
1, a kind of smooth reflection law experimental provision, it is characterized in that: it is by base (1), shell (2), left side optical screen plate (11) and right optical screen plate (12) are formed, on base (1), be provided with eyeglass (7), on the front side board of shell (2), be provided with smog hole (9), be flexible connection between left side optical screen plate (11) and the right optical screen plate (12), right optical screen plate (12) is fixed on the eyeglass (7), the lower right corner of left side optical screen plate (11) is provided with breach (8), pull lever (10) is fixed on the left optical screen plate (11), right optical screen plate (12) be provided with magnetic stripe plate (4) inside, laser pen (3) adsorbs on it.
