Abstract

The utility model pertaining to physics experiment devices is particularly related to a simple experiment instrument for total optical reflection, which is essentially consisted of an electric torch (1), a container for holding water (3), water and a container for receiving water (7). Masking paper (2) is arranged on the inner wall of the container for holding water (3) to wrap the inner wall, and 2cm-thick cotton or fine sand is positioned at the bottom the container for holding water (3), a water exit hole (6) is provided on the lower end wall of the container for holding water (3), the container for receiving water (7) is positioned under the container for holding water (3), and the electric torch is positioned above the water (4) in the container for holding water (3). With simple structure, easy operation and low price, the simple experiment instrument for total optical reflection can be self-made, and is particularly suitable for middle school students in countryside to do physics experiments.

Description

The total reflection experimental provision of simple and easy light

Technical field

The utility model belongs to physics facility, particularly a kind of total reflection experimental provision of simple and easy light.

Technical background

In Physical Experiment, the experimental apparatus of optics is a lot, but all costs an arm and a leg mostly, generally all be cannot afford in the middle school in some rural areas, have to abandon experiment, makes intuitively some physical phenomenon of student, is a kind of loss to the student, also the remote effect quality of instruction.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned technical deficiency, and a kind of total reflection experimental provision of cheap, practical simple and easy light is provided.

The technical scheme that the utility model technical solution problem adopts is: the total reflection experimental provision of simple and easy light mainly is made up of torch, water container, water and water receiving container, be characterized on the inwall of water container, enclosing the dress light-shielding sheet, place thick cotton or the fine sand of 2cm in the bottom, on the lower end wall of water container, establish an apopore, below water container is oblique, place the water receiving container, the top placement torch of water in the water container.

The beneficial effects of the utility model are: simple in structure, the processing ease, cheap of the total reflection experimental provision of simple and easy light, can make by oneself, and be particularly suitable for the rural middle school life and do Physical Experiment usefulness.

Description of drawings

Specify with embodiment below in conjunction with accompanying drawing.

Fig. 1 shows that the total reflection experimental provision structure office of simple and easy light cuts open figure.

Among the figure, the 1-torch; The 2-light-shielding sheet; The 3-water container; 4-water; The 5-fine sand; The 6-apopore; 7-water receiving container;

Embodiment

Embodiment, with reference to accompanying drawing 1, the water container 3 of the total reflection experimental provision of simple and easy light can be made with metal or plastics, make and square or circularly all can, if will enclose dress light-shielding sheet 2 at the water container inwall with plastics, thick cotton of 2cm or fine sand 5 are put in the bottom in water container 3, in order to shading.In water container 3, adorn 3/4 water 4, place torch 1 for waterborne, on water container 3 lower end walls, establish the apopore 6 of a diameter 2mm, put a water receiving container 7 below tiltedly at apopore 6.Be preferably in during experiment and carry out better effects if in the darkroom, discharge water and opened torch 1 at 4 o'clock simultaneously, light penetrates with water 4.

Claims

1, a kind of total reflection experimental provision of simple and easy light mainly is made up of torch (1), water container (3), water and water receiving container (7), it is characterized in that on the inwall of water container (3), enclosing dress light-shielding sheet (2), place thick cotton or the fine sand (5) of 2cm in the bottom, on the lower end wall of water container (3), establish an apopore (6), below water container is oblique, place water receiving container (7), the top placement torch (1) of water (4) in the water container (3).
