Abstract
The utility model belongs to a teaching experiment device, in particular to a light total-reflection experiment device used in physics teaching, which is composed of a flashlight 1, a water container 5 and clean water 9, a black light shielding layer is arranged fixedly on inner wall of the water container 5, and a layer of white thin sand 8 is arranged at the bottom of the water container 5; and the upper part of the water container 5 is provided with a water inlet nozzle 4, the lower part of the water container 5 is provided with a water outlet hole 6, and the water outlet hole 6 is tightly matched with a water outlet hole cover 7. The experiment device has simple structure, self-made property and easy operation; total reflection effect of light is obvious and visual, and advantageous for students to understand and remember, moreover the utility model can improve optical teaching experiment of physics.
Description
Technical field
The utility model belongs to experiment device for teaching, the total reflection experimental provision of the light that particularly a kind of physics teaching is used.
Background technology
In physics teaching in secondary school, optics is the important component part of physics course, in teaching, because the shortage of experimental facilities can only be told about in the classroom, the student sounds and feels abstract, be unfavorable for memory and profound understanding, make teaching efficiency bad, influence quality of instruction.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, and a kind of self-control simple in structure, convenient is provided, and makes the student learn the total reflection phenomenon that optics can intuitively be seen light, strengthens the total reflection experimental provision of the light of student's understanding and memory.
The technical scheme that the utility model technical solution problem adopts is: a kind of total reflection experimental provision of the light of being made up of torch, water container and clear water, be characterized on the inwall of water container the fixedly light shield layer of one deck black, place the fine sand of one deck white in the bottom; Establish a water inlet tap on water container top, the bottom is provided with apopore, and the apopore wringing fit is stamped the water outlet port lid.
The beneficial effects of the utility model are: this experimental provision is simple in structure, can make easy operating by oneself; The total reflection effect of light obviously, intuitively, and is very favourable to student's understanding and memory, can improve its physical optics quality of instruction.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 is the total reflection experimental provision front view of light.
Among the figure, the 1-torch; The 2-switch; The 3-loam cake; The 4-faucet; The 5-water container; The 6-apopore; 7-water outlet port lid; The 8-fine sand; The 9-clear water; The 10-light shield layer; The 11-lampshade;
Embodiment
With reference to accompanying drawing, a kind of total reflection experimental provision of light is made up of torch 1, water container 5 and clear water 9, is characterized on the inwall of water container 5 the fixedly light shield layer 10 of one deck black, places the fine sand 8 of one deck white in the bottom; Establish a water inlet tap 4 on water container 5 tops, the bottom is provided with apopore 6, and apopore 6 wringing fits are stamped water outlet port lid 7.Loam cake 3 centers are provided with hole torch 1 and pass the hole and be threaded with lampshade 11, cover on water container 5, and torch 1 is provided with switch 2, and it is 2cm that fine sand 8 is contained in water container 5 bottom thickness, also available white cotton; Put into clear water 9 by faucet 4 in the water container 5, clear water 9 is put into water container about 5 3/4.During experiment, open and close 2, make the water surface of the light directive clear water 9 of torch 1, torch 1 also can change other light source into, opens water outlet port lid 7 again, and clear water 9 can flow out from apopore 6, and light penetrates with clear water 9, can see a luminous water column; Experimentize in the darkroom, effect is best.
