Base 3 is placed to the center department on 1 surperficial of carousel, and fixed being equipped with first glass board 4 on the base 3, when placing base 3, lets the center of first glass board 4 bottom surfaces be in the zero scale department of scale, and the long limit is perpendicular with the scale, makes first glass board 4 divide into two parts with the scale equidistribution.
The working principle is as follows:
a light source, such as a burning candle, is placed on the rotary table 1 along the scale of the scale, the candle is positioned on one side of the first glass plate 4, an image of the light of the candle behind the glass plate can be seen, then a candle with the same height without burning is moved on one side of the first glass plate 4 where the candle is not placed, the candle without burning is overlapped with the image of the burning candle, and then the distance between the two candles relative to the first glass plate 4 is observed by using the scale. The image that the candle appears on the level crossing is the virtual image, and the distance between virtual image and the real image is unable measurable in reality, but in this embodiment, although the formation of image of candle body is unclear on transparent glass board, the flame of candle burning is clear enough, and another candle of not burning such as equal altitude makes its candle head coincide with flame, and the candle that does not burn is just equivalent to the virtual image of burning candle. The virtual image position which cannot be directly observed is displayed through the experiment, so that students can visually observe the position relation between the real image and the virtual image. Because the position of every student is different in the classroom, the angle of observing the experimental phenomenon is different, rotate carousel 1 and can make things convenient for the student of different positions to both can follow forward angle observation experimental phenomenon, or the student observes the experiment from many angles in an experiment.
Example 2:
this example was further optimized based on example 1.

The provision of the pads 101 makes the rotation of the turntable 1 smoother.
Example 3:
the present embodiment is further optimized based on the above embodiments.
An inner rotary disc 102 is arranged on the rotary disc 1, and the inner rotary disc 102 is a circular ring concentric with the rotary disc 1 and rotates relative to the rotary disc 1. When the turntable 1 is rotated, the inner dial 102 on the turntable 1 is rotated together with it, and at the same time, the inner dial 102 can be rotated alone, so that the inner dial 102 is rotated with respect to the turntable 1.
The working principle is as follows:
the base 3 and the first glass plate 4 were placed in the same manner as in example 1, the lighted candle was placed on the inner dial 102, and after seeing the image of the candle light behind the glass plate, a candle of the same height as the candle that did not burn was moved on the side of the first glass plate 4 where the candle was not placed, so that the candle that did not burn coincided with the image of the candle that burned. The distance of each of the candles from the first glass plate 4 was then observed using a ruler. Unlike example 1, the inner dial 102 was also rotated to change the relative position between the burning candle and the first glass plate 4, and the candle that did not burn was moved again to overlap the images of the two candles on both sides of the first glass plate 4, and the distance between the two candles relative to the first glass plate 4 was observed using a ruler. After experimental tools such as glass plate, candle are placed on the turntable 1, the relative position between candle and glass plate can be changed by simply rotating the inner turntable 102, and a plurality of groups of experimental data can be rapidly and conveniently acquired.
Example 4:
the present embodiment is further optimized based on the above embodiments.
A second glass plate 5 is further arranged on the base 3, and the second glass plate 5 is attached to the first glass plate 4; a first mirror paper 401 is arranged in the area of one fourth to two fifths of the lower part of the first glass plate 4; a second mirror paper 501 is arranged on one fourth to two fifths of the area above the second glass plate 5. The mirror paper on the two glass plates does not occupy half area of the glass plates, so that the two glass plates are attached to each other, and a transparent part is arranged in the middle of the two glass plates.
First mirror surface paper 401 is established on first glass board 4 with the one side of the laminating of second glass board 5, second mirror surface paper 501 is established and is kept away from the one side of first glass board 4 on second glass board 5. The two mirror paper are not on the same horizontal plane, namely the reflecting surfaces are not on the same horizontal plane.
The working principle is as follows:
when only using first glass board 4 demonstration light level crossing formation of image principle, the height of candle is higher than first mirror surface paper 401, can be clear observe the candle body of candle on first mirror surface paper 401, although can not clear see the candle body in the transparent region of first glass board 4, flame is very clear, the image on first mirror surface paper 401 and the image on the transparent region of first glass board 4 are the virtual image, but mirror surface paper can't confirm the position that the virtual image is located, and the image on the transparent region of first glass board 4 can be through placing the equal altitude candle in the back of first glass board 4 and confirm the position, draw the demonstration content from this.
When the embodiment is used for observing the reflection phenomenon of light, another experiment can be carried out only by adding the second glass plate 5, and the preparation work of teachers is reduced. During demonstration, the base 3 is arranged at the center of the turntable 1. Three laser pens are fixed on a laser pen rack 6, the three laser pens respectively and obliquely irradiate light in three areas of the first mirror paper 401, the second mirror paper 501 and the middle transparent position, and then spray or smoke is made, such as dry ice and the like, so that the path of the light is more obvious.
Because the first mirror paper 401 and the second mirror paper 501 are not on the same horizontal plane, under the condition of smoke, the difference of the incident point of the light in two places can be obviously observed, namely, students can clearly distinguish and visually see the position of the imaged mirror, and then the object distance and the image distance can be accurately calculated. In the area where the middle of the glass plate is transparent, the image on the transparent glass plate is also clearly observed to be darker than the image on the specular paper, but the light emitted from the transparent glass plate is brighter than the light emitted from the specular paper.
