Abstract
Provided is a demonstration device for the imaging rule of a concave mirror. The demonstration device comprises a concave mirror body, an electric candle, an imaging plate and an electric device. The electric device comprises guide rails, sliding blocks and a motor. The guide rails include an upper guide rail and a lower guide rail. The sliding blocks are arranged on the guide rails. The motor is connected with the sliding blocks. The upper guide rail and the lower guide rail are respectively arranged on the upper end and the lower end of the same side of the concave mirror body. The electric candle is arranged on the sliding block on the lower guide rail. The imaging plate is arranged on the sliding block on the upper guide rail. The movements of the electric candle and the imaging plate are manually controlled, the demonstration is vivid and more interesting, the imaging rule of the concave mirror is more visually and profoundly demonstrated in an interactive manner, and the demonstration device is especially applicable to science popularization demonstration.
Description
Technical field
The utility model relates to a kind of exhibiting device, relates to specifically a kind of exhibiting device of concave mirror imaging law.
Background technology
The imaging of concave mirror is catoptric imaging, becomes the virtual image upright, that amplify when object is less than focal length, object from minute surface more close to, picture is less, not imaging when object distance equals one times of focal length, the real image that becomes to stand upside down and amplify when object distance is between one, two times of focal length, object from minute surface more away from, as less; Equal the large real images that stand upside down such as two times of focal length Shi Cheng when object distance; When object distance is greater than 2 times of focal lengths, the real image that become to stand upside down, dwindles, object from minute surface more away from, as less; The real image become and object are at homonymy, and the virtual image of one-tenth and object are at heteropleural; Concave mirror not only can make parallel rays converge at focus, and the light reflection that can also make focus send becomes directional light.
Former science popularization show in to the introduction of concave mirror imaging, the most use allows spectators observe imaging under the state of object static state, this kind of display form is when introducing the rule of concave mirror imaging, lack continuity, can not introduce comprehensively, intuitively the concave mirror imaging law, and lack interest, can't comprehensively embody the form that modern science popularization is showed.
The utility model content
The purpose of this utility model be for solve in prior art in science popularization to the displaying of concave mirror imaging law from defect, provide a kind of exhibiting device of concave mirror imaging law to solve the problems referred to above.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of exhibiting device of concave mirror imaging law, it is characterized in that: comprise concave mirror body, Electric camdle, imaging plate, electric device, described electric device comprises guide rail, slide block, motor, described guide rail is divided into upper rail and lower guideway, described slide block is located on guide rail, and described motor is connected with slide block, and described upper rail and lower guideway are located at the two ends up and down of concave mirror body the same side, described Electric camdle is located on the slide block of lower guideway, and described imaging plate is located on the slide block of upper rail.
The exhibiting device of above-mentioned a kind of concave mirror imaging law is characterized in that: also comprise the control power supply, described control power supply is connected with motor with Electric camdle respectively.
The exhibiting device of above-mentioned a kind of concave mirror imaging law is characterized in that: also comprise control lever, the quantity of described control lever is 2, and described control lever is connected with motor by controlling power supply.
The exhibiting device of above-mentioned a kind of concave mirror imaging law is characterized in that: also comprise switch, described switch is located on control lever, and described switch is connected with Electric camdle by controlling power supply.
The beneficial effects of the utility model are: by the movement of manual control Electric camdle and imaging plate, exhibition method is lively, and more interesting, more intuitively, the rule of profoundly by interactive form, showing the concave mirror imaging, is particularly useful for science popularization and shows.
