Each feature operation process of the present utility model is as follows:
For demonstrating feature and the principle of mirror imaging, as shown in Figure 1, during use, glass plate 1 is extracted out inside case mouth 6, the centre position of the top board 4 of casing 6 is arranged on by glass plate fixed mount 2, the LED miniature bulb 5 being stained with magnet bottom one is placed above iron sheet layer 21 before glass plate 1, open the switch of this LED miniature bulb 5, the feature of symmetrical virtual image is become according to level crossing, students' union observes virtual image and LED miniature bulb profile is full symmetric, now, the LED miniature bulb 22 that another has opened switch can be placed in the position of virtual image, virtual image overlaps with this LED miniature bulb 22, student just can measure two LED miniature bulbs 5 clearly, 22 to glass plate 1(and minute surface) distance be equidistant.
In addition, top board 4 can as shown in Figure 6, can be opened, multi-angle rotation, allows full class classmate observe clearly in each corner to facilitate.
For demonstration light is linearly propagated, mirror-reflection and diffuse reflection, convex lens to the convergence effect of light and concavees lens to the disperse function of light, as Fig. 3, shown in Fig. 4, first glass plate 1 is promoted along groove 25, be placed on window inner side position, then by the first optical frames part 27, two laser lamps be parallel to each other 30 are by son, female magnet 28, the adhesive effect of 29, be separately fixed on the inside surface of glass plate 1, santal in smoke canisters 26 is lighted and is placed in casing 6, open two laser lamp 30 switches, then chamber door 11 is closed, under the environment of smog, through glass plate 1, can see that the light of laser lamp 30 is linearly propagated clearly, by converting the first dissimilar optical frames part, and move female magnet 29 flexibly, with mobile two laser lamps 30, the position of the first optical frames part 27, makes the reflection of laser rays, refraction distance or angle reach optimal viewing, just can the mirror-reflection of clear demonstration light and diffuse reflection, concave mirror, convex lens are to the convergence effect of light and convex mirror, concavees lens are to the disperse function of light.
For demonstration mirror imaging principle, enliven course atmosphere, teacher can carry out " optical magic ", as shown in Figure 2, the level crossing 24 that a back side is provided with light shield layer is placed in casing 6, the minute surface of level crossing 24 is towards vertical, transparent glass plate 1 is placed, and with tank floor in angle of 45 degrees, observed by window, overall picture in an imaginary casing 6 can be seen, because according to mirror imaging principle, void that level crossing presents " as " be casing inner bottom surface in fact, due to side each in chest, bottom surface color, material indistinction, visually see, the imperceptible existence having level crossing, only see the casing 6 of " absolutely empty ", then, chamber door 11 is closed, one card or small article are dropped in casing 6 from strip through hole 23, card or small article to fall between level crossing 24 and after panel box 16 in space in fact, but students' union is obviously seen has card or small article to drop in casing, but the casing of " absolutely empty " is only seen, can't see card or small article, thus greatly motivate students' interest in learning, students' union probes into its inherent optical principle gamely.
For demonstration pinhole imaging system principle, as Fig. 1, shown in Fig. 5, rule 13 is extracted out a part from putting chi groove 10, U-shaped support 14 is stuck in rule 13 sections, electric torch 15 is arranged on U-shaped support 14, twitch the hard scraps of paper 35, make the aperture 33 be arranged on the hard scraps of paper 35, 34 centers letting alone an aligning light hole 19, open electric torch 15, the luminescence of electric torch is made to rectify the triangular apertures 33 on the hard scraps of paper or circular aperture 34, open chamber door 11, in casing 6, optical screen 9 is placed in the front of light hole 19, close chamber door 11, shift scale chi 13 forward or backward, the light source picture that electric torch stands upside down will be seen clearly on optical screen 9, this light source is as shape and triangular apertures 33, the shape of circular aperture 34 has nothing to do, and, when rule 13 changes apart from casing distance size, the size of light source picture also changes thereupon, i.e. pinhole imaging system principle.
For demonstration convex lens, concavees lens, water lens imaging principle, be also our camera sayed at ordinary times, lantern slide principle and myopia, presbyopic formation basic theory.As Fig. 1, shown in Fig. 7, first, rule 13 is extracted out a part from putting chi groove 10 bottom casing 6, U-shaped support 14 is stuck in rule 13 sections, electric torch 15 is arranged on U-shaped support 14, install the second optical frames part 37, finally again chamber door 11 is closed, debug complete, open electric torch 15, shift scale chi 13, the spacing of adjustment rule 13 and casing 6, be equivalent to adjust " object distance ", convert the second dissimilar optical frames part 37, i.e. convex lens, concavees lens, water lens any one, according to aforementioned operation, just intuitively can see convex lens, concavees lens, water lens imaging feature, also be our camera sayed at ordinary times, lantern slide principle and myopia, presbyopic formation basic theory.Student changes according to the numeral of the size of rule 13, through teacher user, just can sum up imaging characteristics and object distance, at a distance of between rule.
Whether optical screen 9 is arranged depending on image-forming range, when image-forming range allows, an optical screen 9 can be set in casing 6, before light hole 19, when image-forming range is larger, then need not arrange optical screen 9, the light of electric torch 15 penetrates outside casing through light hole 19, second optical frames part 37, glass plate 1, window 8, adjust whole casing, be equivalent to adjust " apart ", imaging is presented on metope or on the outer curtain of casing 6, and observation of students is got up complete display.All accessories of the present utility model, as the first optical frames part 27, second optical frames part 37, laser lamp 30, fixed mount 2, female magnet 29, smoke canisters 26 etc., all can be placed in casing 6, compact, easy to carry.
