Mobile, the upper end of the metal snake-like hose 5 is installed with generating laser 6, and metal snake-like hose 5 front and rear can adjust curved
The angle of degree, the further light that regulation upper end generating laser 6 is projected, a blank sheet of paper is sticked in the right-hand member of the first glass blocks 2,
Be easy to observation, allow the light that the generating laser 6 of the top of metal snake-like hose 5 is sent after the refraction of the first glass blocks 2 just
The junction of the lower edge of the first glass blocks 2 and blank sheet of paper is mapped to, the red light that generating laser 6 is sent is that whole experiment is carried
For light source, horizontal homogeneous offers two chutes 7 on the right side of the upper surface of the mirror board 1, and the internal slide of the chute 7 is installed
There are four sliding blocks 8, the upper surface of the sliding block 8 is closely fitted with the second glass blocks 9, and the second glass blocks 9 and the first glass blocks 2
Refractive index it is identical, the left surface of the second glass blocks 9 is smooth, the sliding block 8 that the second glass blocks 9 is brought into close contact by lower section,
It can be horizontally slipped in chute 7, take away blank sheet of paper, keep fixture block 4 motionless, when the second glass blocks 9 slides into high order end with first
Glass blocks 2 is overlapped, and light is reflected after the reflection of mirror board 1 in the second glass blocks 9, is then mapped to and translucent is connect light
On plate 12, when the second glass blocks 9 slides into low order end, the light by the reflection of mirror board 1 is not hindered to shine directly into translucent
Connect on tabula rasa 12, support plate 10 is installed with the right side of the upper surface of the mirror board 1, and support plate 10 is located at the right side of chute 7, branch
Plate 10 be used for supporting and connect it is translucent connect tabula rasa 12, the upper end of the support plate 10 passes through L-shaped connection sheet 11 and horizontal positioned
The translucent tabula rasa 12 that connects is fixedly connected, and translucent to connect the left surface of tabula rasa 12 vertical at one with the right flank of the first glass blocks 2
In plane；
Specifically, the upper surface level of the glass blocks 9 of the first glass blocks 2 and second is smooth, and the He of the first glass blocks 2
The leaving no air bubbles inside of second glass blocks 9, it is ensured that refraction of the light in the first glass blocks 2 and the second glass blocks 9 is not affected,
Reduce the error of experiment.

Row refraction, because the first glass blocks 2 is identical with the refractive index of the second glass blocks 9, the angle of emergence of refraction and the angle of horizontal plane are not
Become, or 30 degree, light is mapped to the translucent lower surface for connecing tabula rasa 12, can see what is irradiated through the translucent tabula rasa 12 that connects
Hot spot, carries out first in the translucent position for connecing the upper surface of tabula rasa 12 correspondence hot spot with marking pen and marks, this first is tagged to
The translucent air line distance for connecing the upper surface left hand edge of tabula rasa 12 is x, and when the second glass blocks 9 slides into low order end, light passes through mirror
The minute surface of panel 1 is directly reflexed on the translucent lower surface for connecing tabula rasa 12, and tabula rasa 12 is connect it can be seen that irradiation through translucent
The hot spot gone out, carries out the second mark, this second mark with marking pen in the translucent position for connecing the upper surface of tabula rasa 12 correspondence hot spot
It is y to remember the translucent air line distance for connecing the upper surface left hand edge of tabula rasa 12, and the distance of two hot spots is x-y, can directly be observed
Go out light skew caused by refraction, because the angle of emergence is 30 degree, AC sides areIt is directly anti-by the minute surface of mirror board 1
The light and the angle of normal penetrated are arctanRefraction angle phase of this angle with light in the first glass blocks 2
Together, so that the refractive index for obtaining the first glass blocks 2 and the second glass blocks 9 is 1/ { 2sin arctanThis practicality
New type of safe is practical, simple to operate, student can be allowed to be operated, and intuitively can see the skew that anaclasis is produced by light, ask
Go out the refractive index of glass blocks, student is produced sense of accomplishment, and then increase to optical learning confidence, more preferable learning physicses light
Learn.
