Abstract
The utility model provides a light refraction demonstrator which can be used conveniently. The light refraction demonstrator is used for teaching demonstration and comprises a supporting rack; a container is fixedly connected with the supporting rack; the container is internally provided with two protractors; the linear edges of the two protractors correspond to each other and are bonded with each other; the radian edges of the two protractors are connected with the internal surface of the container; the container is internally filled with liquid and gas; and the supporting rack is connected with a laser lamp by a connecting rope.
Description
Technical field
The utility model relates to a kind of realia, relates in particular to a kind of refraction demonstration device of light.
Background technology
Light enters another kind of medium by a kind of medium or when propagating in a kind of inhomogeneous medium, the phenomenon of direction generation deviation is called the refraction of light, when the teacher does experiment at present, all be with a glass jar carrying liquid, pass liquid with laser lamp then, allow the refraction effect of observation of students light, the demonstration effect is unintelligible, the demonstration path is inhomogeneous, interrupts easily, uses trouble.
Summary of the invention
The purpose of this utility model provides a kind of refraction demonstration device of light easy to use.
For achieving the above object, the technical solution adopted in the utility model is: a kind of refraction demonstration device of light, comprise bracing frame, it is characterized in that: be placed with container on the bracing frame, two protractors are housed in the container, the straight line of two protractors is corresponding, the straight line of two protractors is bonding mutually, and the radian limit of two protractors is connected with the inside surface of container, and liquid is housed in the container, gas also is housed in the container, is connected with laser lamp by connection cord on the bracing frame.
In this structure, have liquid injection port on the container, design has container cover on the liquid injection port.
In this structure, bracing frame is fixedlyed connected with container.
In this structure, the height of liquid is identical with the height of the straight line of protractor.
The utility model has the advantages of and be: owing to be placed with container on the bracing frame in the utility model, two protractors are housed in the container, the straight line of two protractors is corresponding, the straight line of two protractors is bonding mutually, the radian limit of two protractors is connected with the inside surface of container, liquid is housed in the container, gas also is housed in the container, be connected with laser lamp by connection cord on the bracing frame, so can occur the route of transmission of light when using the utility model lastingly, can make the student clearly see the phenomenon of direct projection, the demonstration effect is clear, and the demonstration path is even, and do not interrupt, good demonstration effect helps studying the refraction law of light, and is easy to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
In the accompanying drawing: 1, bracing frame; 2, container 3, liquid 4, protractor 5, container cover 6, connection cord; 7, laser lamp.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
The utility model as shown in Figure 1, a kind of refraction demonstration device of light, comprise bracing frame 1, be placed with container 2 on the bracing frame 1, two protractors 4 are housed in the container 2, the straight line of two protractors 4 is corresponding, the straight line of two protractors 4 is bonding mutually, and the radian limit of two protractors 4 is connected with the inside surface of container 2, and liquid 3 is housed in the container 2, gas also is housed in the container 2, be connected with laser lamp 7 by connection cord 6 on the bracing frame 1, when using the utility model, the utility model level be placed on the desk, inject light along the scale of protractor then, light is injected along the direction of scale mark, owing in the container 2 gas is housed also, so can be clearly seen that incident ray, observe the size of incident angle, when incident light enters liquid by gas then, can clearly observe refracted ray, observe the size at refraction angle, observing effect is good, and is easy to use.
In the present embodiment, have liquid injection port on the container 2, design has container cover 5 on the liquid injection port, and liquids and gases can inject in the container by liquid injection port, and is convenient happy;
In the present embodiment, bracing frame 1 is fixedlyed connected with container 2;
In the present embodiment, the height of liquid 3 is identical with the height of the straight line of protractor 4.
When using the utility model, can also replace the interior liquid of container, allow the refraction effect of light in the observation of students different medium with liquid of different nature.
