Abstract
The utility model belongs to a physics teaching demonstrator for light reflection and refraction. The utility model provides the demonstrator for light reflection and refraction with the advantages of obvious show effects and convenient operation. The utility model comprises a glass box body. The utility model has the essential structure that the box body is divided into an upper air chamber, a water chamber and a lower air chamber from the top to the bottom. The side faces of the upper air chamber and the lower air chamber are respectively provided with smoke inlet holes. A plane mirror is arranged on the bottom side of the upper air chamber. A slide way on a support frame above the upper air chamber is provided with a laser device. The bottom and the side faces of the lower air chamber are respectively provided with regulating screws and doors.
Description
Technical field:
The utility model is to belong to the physics teaching demonstration instrument.
Background technology:
Existing reflection of light, refraction demonstration device all adopt the dull and stereotyped way that receives light, and are to demonstrate in normal air, the demonstration DeGrain, and it is also very difficult to operate.
The utility model content:
The utility model is exactly at the problems referred to above, and obvious, the easy to operate reflection of light of a kind of display effect, refraction demonstration device are provided.
The utility model adopts following technical scheme: the utility model comprises the glass casing, its structural feature is that casing is divided into air chamber, water cavity, following air chamber from top to down, the side of last air chamber, following air chamber is provided with smoke intaking hole respectively, on the bottom surface of last air chamber level crossing is set, slideway on the support of the top of last air chamber is provided with laser instrument, and the bottom of following air chamber and side are provided with respectively adjusts screw, door.
The beneficial effects of the utility model:
The utility model makes the flat board demonstration of existing light become three-dimensional demonstration, and can add smog in air chamber, and is with milk etc. in water, makes the light path clear performance; Be that reflection of light, refraction display effect are obvious, and easy and simple to handle, can reach good teaching efficiency.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The utility model comprises glass casing 2, casing 2 is divided into air chamber 7, water cavity 5, following air chamber 4 from top to down, the side of last air chamber 7, following air chamber 4 is provided with smoke intaking hole 6 respectively, level crossing 9 is set on the bottom surface of last air chamber 7, slideway 11 on the support 10 of the top of last air chamber 7 is provided with laser instrument 12, and the bottom of following air chamber 4 and side are provided with respectively adjusts screw 1, door 3.
Below in conjunction with a description of drawings course of action of the present utility model:
During the demonstration reflected light:
At first, level crossing 9 is placed the bottom of air chamber 7, build loam cake 8; Be sprayed onto some smog of air chamber 7 by smoke intaking hole 6, open laser instrument 12 on the good slideway 11 of adjusted, can be in last air chamber 7 the clear light path that shows reflection;
The refraction of demonstration light:
At first, take out level crossing 9; In water cavity 5, be filled to and require height, adjust the adjustment screw 1 of casing 2 bottoms, make it casing 2 levels; In water, drip several milk then, and stir; Upwards air chamber 7 is imported low smoke again; Open the laser instrument 12 on the slideway 11 that has mixed up again, can show light path at last air chamber 7, water cavity 5 and reflect situation clearly;
Below level crossing 9 places water cavity 5, can demonstrate refraction, reflection, refraction experiment.
