Abstract
The utility model discloses a kind of geometric figure optical illusion demonstrator, comprise base plate, major arc is arc, minor arc is arc, guide rail, base plate is rectangle, major arc is arc will justify the two parts be divided into the arc string of a musical instrument for same circle of minor arc, major arc is arc and minor arc is arc is all located at backplate surface, the arc axis of symmetry of the arc and minor arc of major arc overlaps and along the long side direction of base plate, wherein minor arc is arc is fixed on the left of backplate surface, the arc guide rail link joint by being located at its back side of major arc is on the right side of backplate surface and can be moved to the left along guide rail and arcly with minor arc be merged into circle.The utility model can hang on all kinds of scientific and technological venue, by observing and operation, is conducive to deepening the understanding to geometric figure optical illusion phenomenon.
Description
Technical field
The utility model belongs to experimental demonstration device technical field, relates to a kind of optical illusion phenomenon demonstrator, is specially a kind of geometric figure optical illusion demonstrator.
Background technology
Optical illusion is when people observe some object, based on empiricism or improperly with reference to the false judgment formed and perception.The kind of optical illusion has a lot, as color optical illusion, motion optical illusion, geometrical optical illusion etc.Optical illusion all has a wide range of applications in fields such as physics, physiology, architectural design, product design and traffic safety.Design optical illusion apparatus for demonstrating, is conducive to the content enriching activity to popularize scientific knowledge, excites student to probe into the interest of science secret.At present, lack a kind of clear demonstration and be conducive to verifying the special demonstration equipment of optical illusion.
Summary of the invention
The purpose of this utility model is the geometric figure optical illusion demonstrator designing the clear demonstration of a kind of energy and be conducive to illusion resolution.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: comprise base plate, major arc is arc, minor arc is arc, guide rail, described guide rail is made up of slide rail and slide block, base plate is rectangle, major arc is arc will justify the two parts be divided into the arc string of a musical instrument for same circle of minor arc, major arc is arc and minor arc is arc is all located at backplate surface, the arc axis of symmetry of the arc and minor arc of major arc overlaps and along the long side direction of base plate, wherein minor arc is arc is fixed on the left of backplate surface, the arc guide rail link joint by being located at its back side of major arc is on the right side of backplate surface and can be moved to the left along guide rail and arcly with minor arc be merged into circle.
Preferentially, the arc minor arc institute of described minor arc is 2 π/3 to central angle, and the arc major arc institute of major arc is 4 π/3 to central angle.
The beneficial effects of the utility model are: major arc is arc separate with minor arc is arc time, clearly can experience optical illusion phenomenon, namely arc the and minor arc of major arc arc seeming is not two parts of same circle; By arc for major arc be pushed into left with minor arc arc be merged into circle time, the resolution of illusion can be carried out.The utility model can hang on all kinds of scientific and technological venue, by observing and operation, is conducive to deepening the understanding to geometric figure optical illusion phenomenon.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is formation schematic diagram of the present utility model while separating with minor arc is arc (major arc is arc).
Fig. 2 is the schematic diagram while being merged into circle with minor arc is arc (major arc is arc) of the utility model checking optical illusion.
In figure: 1. base plate, 2. major arc is arc, and 3. minor arc is arc, 4. guide rail, 41. slide rails, 42. slide bars, 231. axis of symmetry.
Embodiment
As shown in Figure 1, the utility model comprises base plate 1, major arc arc 2, minor arc arc 3, guide rail 4, guide rail 4 is made up of slide rail 41 and slide block 42, base plate 1 is rectangle, major arc arc 2 and minor arc arc 3 are two parts that circle is divided into by a string of a musical instrument of same circle, base plate 1 surface is all located at by major arc arc 2 and minor arc arc 3, wherein minor arc arc 3 is fixed on the left of base plate 1, the axis of symmetry 231 of major arc arc 2 and minor arc arc 3 overlaps, the direction of axis of symmetry 231 is along the long side direction of base plate 1, the slide rail 41 of guide rail 4 is fixed on the right side of base plate 1 along axis of symmetry 231 direction, slide block 42 is fixed on the back side of major arc arc 2 and can horizontally slips along slide rail 41.In Fig. 1, major arc arc 2 and minor arc arc 3 seem not to be two parts of same circle.
As shown in Figure 2, promote major arc arc 2 left, make major arc arc 2 move to minor arc arc 3 along guide rail 4 and merges and become a circle, the optical illusion before verifying thus.
Preferentially, the minor arc institute of minor arc arc 3 is 2 π/3 to central angle, and the major arc institute of major arc arc 2 is 4 π/3 to central angle.
