Description

Reflection of light refraction one demonstration device

Technical field

The utility model relates to a kind of demonstration device, relates in particular to a kind of reflection of light refraction one demonstration device.

Background technology

Light changes the direction of propagation and returns the phenomenon in the original material again on two kinds of material interphases; Be called reflection of light; Light gets into another kind of medium by a kind of medium or when in a kind of inhomogeneous medium, propagating, the phenomenon of direction generation deviation is called the refraction of light, and the teacher is when explanation reflection law and refraction law; Can't explain clearly, be difficult to make students understand.

Summary of the invention

The purpose of the utility model provides a kind of reflection of light refraction one demonstration device that can clear, lasting, evenly show light path.

For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: a kind of reflection of light reflects the one demonstration device, comprises the glass jar of upward opening, and it is characterized in that: solution is equipped with in described glass jar bottom; Horizontal fixed is connected with level crossing in the glass jar; Be designed with the space between the front surface of level crossing and the antetheca of glass jar, level crossing is corresponding with the center of disk, is sealedly connected with loam cake on the glass jar; The inside surface of the antetheca of glass jar is fixedly connected with disk, and gas also is housed in the glass jar.

The utility model has the advantages of and be: because this structure of the utility model, so use the utility model can be clear, lasting, uniformly light path is displayed, help the demonstration of reflection of light law, refraction law, the student is understood easily.

Description of drawings

Fig. 1 is the structural representation of the utility model.

In the accompanying drawing: 1, disk; 2, solution; 3, glass jar; 4, level crossing; 5, loam cake.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further:

The utility model is as shown in Figure 1; A kind of reflection of light refraction one demonstration device; Comprise the glass jar 3 of upward opening, it is characterized in that: solution 2 is equipped with in described glass jar 3 bottoms, and horizontal fixed is connected with level crossing 4 in the glass jar 3; Be designed with the space between the antetheca of the front surface of level crossing 4 and glass jar 3, level crossing 4 is corresponding with the center of disk 1.Be sealedly connected with loam cake 5 on the glass jar 3, the inside surface of the antetheca of glass jar 3 is fixedly connected with disk 1, and gas also is housed in the glass jar 3.

When using the utility model, to the utility model injection laser, laser is injected along the circular dial scale line that is carved with angle then with laser lamp, owing in the fiberglass gas is housed also; So can be clearly seen that incident ray, observe the size of incident angle, when incident light gets into liquid by gas then; Can clearly observe refracted ray, observe the size at refraction angle, observe the reflection ray of incident ray simultaneously through level crossing; Also can observe the size of reflection angle, observing effect is good, and is easy to use.

Claims

1. a reflection of light reflects the one demonstration device; The glass jar (3) that comprises upward opening; It is characterized in that: solution (2) is equipped with in described glass jar (3) bottom, and the interior horizontal fixed of glass jar (3) is connected with level crossing (4), is designed with the space between the antetheca of the front surface of level crossing (4) and glass jar (3); Level crossing (4) is corresponding with the center of disk (1); Be sealedly connected with loam cake (5) on the glass jar (3), the inside surface of the antetheca of glass jar (3) is fixedly connected with disk (1), and glass jar also is equipped with gas in (3).
