Abstract
The utility model discloses a kind of Flat mirror imaging demonstration instrument, comprise the first base plate and the second base plate, between described the first base plate and the second base plate, be provided with hinge, the inside edge of described the first base plate is provided with fixed block, on described fixed block, be fixed with a clear glass, the length direction of described the first base plate is provided with the first slide rail, described the first slide rail is provided with the first slide block, on described the first slide block, be fixed with the first candle, the length direction of described the second base plate is provided with the second slide rail, described the second slide rail is provided with the second slide block, on described the second slide block, be fixed with the second candle.The beneficial effect that the utility model is obtained is: (1) is simple in structure, is easy to carry; (2) the utlity model has directly perceived, quantitative feature, can help student to grasp fast the principle of mirror imaging.
Description
Technical field
The utility model relates to a kind of physics teaching demonstrator, particularly a kind of Flat mirror imaging demonstration instrument.
Background technology
At present, in the process of giving lessons at Middle School Physics, conventionally to lecture the principle of mirror imaging, owing to lacking necessary teaching aid, students can not be intuitively, quantitative test " thing " with " as " relation, thereby can not grasp fast this knowledge point.
Summary of the invention
Problem to be solved in the utility model is: provide a kind of simple in structure, measurement " thing " that can be directly perceived, quantitative and " as " between the Flat mirror imaging demonstration instrument of relation.
In order to address the above problem, Flat mirror imaging demonstration instrument of the present utility model, comprise the first base plate and the second base plate, between described the first base plate and the second base plate, be provided with hinge, the inside edge of described the first base plate is provided with fixed block, on described fixed block, be fixed with a clear glass, the length direction of described the first base plate is provided with the first slide rail, described the first slide rail is provided with the first slide block, on described the first slide block, be fixed with the first candle, the length direction of described the second base plate is provided with the second slide rail, described the second slide rail is provided with the second slide block, on described the second slide block, be fixed with the second candle.
For the ease of measuring object distance and image distance, namely convenient determine " thing " with " as " position, on described the first slide rail and the second slide rail, be equipped with length scale, the starting point of described length scale is respectively the intersection of the first slide rail and fixed block and the intersection of the second slide rail and fixed block.
The beneficial effect that the utility model is obtained is: (1) is simple in structure, and the first base plate is connected by hinge with the second base plate, the first base plate and the second base plate can be closed up by hinge, is easy to carry, (2) drive the first candle to move and promote the second slide block and drive the second candle to move by promoting the first slide block, the distance of the first candle and the second candle distance transparent glass is equated, now, the first candle is " thing " in mirror imaging, the second candle be " as ", thereby make students can see intuitively mirror imaging " thing " and " as ", and can learn by the length scale of observing on the first slide rail and the second slide rail, distance between " thing " and clear glass with " as " and clear glass between distance equate, namely in mirror imaging, object distance and image distance equate, in addition, because the first candle is equal with the second candle, can help students to understand in mirror imaging, " thing " with " as " etc. large, therefore the utlity model has directly perceived, quantitative feature, can help student to grasp fast the principle of mirror imaging.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, the first base plate, 2, hinge, 3, the second base plate, 4, the first slide block, 5, the first candle, 6, length scale, 7, the first slide rail, 8, fixed block, 9, clear glass, 10, the second slide rail, 11, the second candle, 12, the second slide block.
Embodiment
As shown in Figure 1, Flat mirror imaging demonstration instrument of the present utility model, comprise the first base plate 1 and the second base plate 3, between described the first base plate 1 and the second base plate 3, be provided with hinge 2, the inside edge of described the first base plate 1 is provided with fixed block 8, on described fixed block 8, be fixed with a clear glass 9, the length direction of described the first base plate 1 is provided with the first slide rail 7, described the first slide rail 7 is provided with the first slide block 4, on described the first slide block 4, be fixed with the first candle 5, the length direction of described the second base plate 3 is provided with the second slide rail 10, described the second slide rail 10 is provided with the second slide block 12, on described the second slide block 12, be fixed with the second candle 11, described the first candle 5 and the second candle 11 equal and opposite in directions, on described the first slide rail 7 and the second slide rail 10, be equipped with length scale 6, the starting point of described length scale 6 is respectively the first slide rail 7 and the intersection of fixed block 8 and the intersection of the second slide rail 10 and fixed block 8.
When concrete demonstration, promoting the first slide block 4 drives the first candle 5 to move and promotes the second slide block 12 and drive the second candle 11 to move, the distance of the first candle 5 and the second candle 11 distance transparent glass is equated, now, the first candle 5 is " thing " in mirror imaging, the second 11, candle be " as ", thereby make students can see intuitively mirror imaging " thing " and " as ", and can learn by the length scale of observing on the first slide rail 7 and the second slide rail 10, distance between " thing " and clear glass 9 with " as " and clear glass 9 between distance equate, namely in mirror imaging, object distance and image distance equate.
In addition, because the first candle 5 and the second candle 11 equate, can help students to understand in mirror imaging, " thing " with " as " etc. large, therefore the utlity model has directly perceived, quantitative feature, can help student to grasp fast the principle of mirror imaging.
