Abstract
The utility model provides the teaching aid of a kind of studying plane mirror imaging law experiment, it is characterized in that: comprise base plate, transparency glass plate, first candlestick, second candlestick, a transparency glass plate is provided with in the middle of described base plate, described first candlestick is positioned at transparency glass plate side, described second candlestick is positioned at transparency glass plate opposite side, the beneficial effects of the utility model are: structure is simple, be easy to carry, use safety, compensate for the deficiency that mirror imaging experiment equipment is done in laboratory, overcome the difficulty that teacher prepares mirror imaging experiment equipment and contrived experiment, specification can demonstrate plane mirror imaging law: namely level crossing becomes the virtual image, picture and thing equal and opposite in direction, image distance equals object distance, picture is vertical with minute surface with the line of thing.
Description
[technical field]
The utility model relates to a kind of teaching aid, particularly relates to the teaching aid of a kind of studying plane mirror imaging law experiment.
[background technology]
In Middle School Physics teaching material, the teaching of " mirror imaging " this chapter, should carry out lecture experiment and the student experimenting of mirror imaging, and student could get a real idea of the rule of mirror imaging.And Shi Yan Shi No has the existing equipment doing mirror imaging experiment.
Therefore, when teaching " mirror imaging " this chapter, teacher must prepare equipment with the plenty of time.But in the short period of time, difficulty gets out satisfied equipment, and often this experiment done becomes on blackboard and says experiment, makes lively, interesting classroom instruction to become uninteresting, stiff.
[utility model content]
The purpose of this utility model is to solve laboratory and does not do the deficiency of " studying plane mirror imaging law " equipment and the teaching aid of a kind of studying plane mirror imaging law experiment that provides.
The utility model is achieved through the following technical solutions: a kind of teaching aid of studying plane mirror imaging law experiment, comprise base plate, transparency glass plate, the first candlestick, the second candlestick, a transparency glass plate is provided with in the middle of described base plate, described first candlestick is positioned at transparency glass plate side, and described second candlestick is positioned at transparency glass plate opposite side.
Further, above described base plate, be also provided with one deck iron sheet, described iron sheet be carved with the mesh lines of decile.
Further, described transparency glass plate comprises a clear glass, is provided with a base below described clear glass, and described base is provided with base magnet.
Further, described first candlestick and the second candlestick include candle cover, candle cover base, candle, and described candle cover below is provided with a candle cover base, be provided with magnet, be inserted with a candle in described candle cover in described candle cover base.
During use, candle on first candlestick is lighted, the position of mobile second candlestick, when the image that the second candlestick and the first candlestick are projected on transparency glass plate overlaps, takes away transparency glass plate, by the decile grid of iron sheet on base plate, very clearly can see that the first candlestick is identical with the distance of the second candlestick and transparency glass plate with the distance of transparency glass plate, can verify that level crossing becomes the virtual image, as with thing equal and opposite in direction, image distance equals object distance, as vertical with minute surface with the line of thing.
The beneficial effects of the utility model are:
1, compensate for the deficiency that mirror imaging experiment equipment is done in laboratory, overcome the difficulty that teacher prepares mirror imaging experiment equipment and contrived experiment.
2, be easy to carry, both can teacher's lecture experiment on classroom, again can in students in class or experiment of doing it yourself after class, experiment effect is significantly interesting, can enrich the content of education greatly, improves efficiency of teaching.
3, can specification demonstration plane mirror imaging law: namely level crossing becomes the virtual image, as with thing equal and opposite in direction, image distance equals object distance, as vertical with minute surface with the line of thing.
4, illustrate that rule is clear, directly perceived.Image distance equals object distance, as vertical with minute surface with the line of thing.Can directly find out on base plate.
5, potential safety hazard is avoided.Because student is when testing, the blank sheet of paper on desk and desk slightly touch, and the candle of burning easily falls down, burn student.This demonstrator has magnet due to candle cover and glass bottom, then not easily fall down when standing on iron sheet plate.Overcome the difficulty of glass and the bad setting of candle, avoid the danger of candle flame burn student.

Reference numeral: 1, base plate; 2, transparency glass plate; 3, the first candlestick; 4, the second candlestick; 11, iron sheet; 21, clear glass; 22, base; 23, base magnet; 31, candle cover; 32, candle cover base; 33, magnet; 34, candle.
[embodiment]
Below in conjunction with the drawings and the specific embodiments, the utility model is described further:
As shown in Figure 1, a kind of teaching aid of studying plane mirror imaging law experiment comprises base plate 1, transparency glass plate 2, first candlestick 3, second candlestick 4, a transparency glass plate 2 is provided with in the middle of described base plate 1, described first candlestick 3 is positioned at transparency glass plate 2 side, and described second candlestick 4 is positioned at transparency glass plate 2 opposite side.
Preferably, above described base plate 1, be also provided with one deck iron sheet 11, described iron sheet 11 be carved with the mesh lines of decile.
Preferably, described transparency glass plate 2 comprises a clear glass 21, is provided with a base 22 below described clear glass 21, and described base 22 is provided with base magnet 23.
Preferably, described first candlestick 3 and the second candlestick 4 include candle cover 31, candle cover base 32, candle 34, are provided with a candle cover base 32 below described candle cover 31, be provided with magnet 33, be inserted with a candle 34 in described candle cover 31 in described candle cover base 32.
During use, candle 34 on first candlestick 3 is lighted, the position of mobile second candlestick 4, when the second candlestick 4 overlaps with the first candlestick 3 image be projected on transparency glass plate 2, take away transparency glass plate 2, by the decile grid of iron sheet 11 on base plate 1, very clearly can see that the first candlestick 3 is identical with the distance of transparency glass plate 2 with the second candlestick 4 with the distance of transparency glass plate 2, can verify that level crossing becomes the virtual image, picture and thing equal and opposite in direction, image distance equals object distance, as vertical with minute surface with the line of thing.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable change and amendment to above-mentioned embodiment.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this instructions, these terms just for convenience of description, do not form any restriction to the utility model.
