Abstract

The utility model belongs to an experiment device for teaching, and particularly relates to a simple experimental device for total light reflection. The simple experimental device comprises a light source lamp (1), a water container (6) and clear water (10), wherein a black layer (11) is coated on the inner wall of the water container (6); a layer of fine sand (9) is disposed at the bottom of the water container (6); the clear water (10) is filled on the fine sand (9); a water outlet (8) is formed on the wall of the water container (6) above the fine sand (9) layer; a water outlet cover (7) is disposed at the water outlet (8); a water inlet pipe (5) is disposed above the wall of the water container (6); a valve (4) is disposed on the water inlet pipe (5); a water container cover (3) is arranged at the top end of the water container (6); the light source lamp (1) is disposed at the centre of the water container cover (3); and a lampshade (2) is disposed outside the light source lamp (1). The simple experimental device for total light reflection is simply structured, can be self-manufactured, is easily operated, takes an obvious and visual effect in testing the total reflection of light, and is beneficial for students to remember and understand optical characteristics.

Description

Simple and easy light total reflection experimental provision

Technical field

The utility model belongs to experiment device for teaching, particularly a kind of simple and easy light total reflection experimental provision.

Background technology

At present, in middle school physical curriculum, optics is important component part, in teacher's teaching process, depends the oral account explanation alone, the student sounds and can feel abstract dull, be unfavorable for memory and profound understanding, influence teaching efficiency, if buy series of physical experiment apparatus, price is very high, especially the rural middle school that falls behind is difficult to accomplish.

Summary of the invention

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

The technical scheme that the utility model technical solution problem adopts is: simple and easy light total reflection experimental provision comprises illuminator, water container, clear water, be characterized on the inwall of water container, establishing the blacking layer, dress one deck fine sand at the bottom of water container, adorn clear water above the fine sand, on the wall that is filled with water above the fine sand layer, set out the mouth of a river, the place sets out water cap at water delivering orifice, above the wall that is filled with water, establish water inlet pipe, water inlet pipe is provided with valve, be provided with the water container lid on the water container top, illuminator is equipped with at water container lid center, and illuminator is provided with lampshade outward.

The beneficial effects of the utility model are: simple and easy light total reflection experimental provision is simple in structure, can make by oneself, and easy operating, the total reflection effect of experiment light obviously, intuitively makes the student very favourable to optical characteristics memory and understanding.

Description of drawings

Specify with embodiment below in conjunction with accompanying drawing.

Fig. 1 is simple and easy light total reflection experimental provision structural drawing.

Among the figure, the 1-illuminator; The 2-lampshade; 3-water container lid; 4-water inlet pipe valve; The 5-water inlet pipe; The 6-water container; 7-water outlet flap; The 8-water delivering orifice; The 9-fine sand; The 10-clear water; 11-blacking layer;

Embodiment

Embodiment, with reference to accompanying drawing 1, water container 6 available metals of simple and easy light total reflection experimental provision or nonmetal circle or other shape made.On water container 6 inwalls, establish blacking layer 11 to cover light.At the bottom surface of water container 6 dress one deck fine sand 9, fine sand 9 is that white is the best, and thickness is about 2cm.Clear water 10 is housed on fine sand 9, sets out the mouth of a river 8 on 6 walls of the water container above the fine sand 9, the outside of water delivering orifice 8 sets out water cap 7.On 6 walls of the water container above the clear water 10, establish water inlet pipe 5, establish water inlet pipe valve 4 on the water inlet pipe 5.Be provided with water container lid 3 on the top of water container 6, illuminator 1 be housed in the centre of water container lid 3, illuminator 1 can with the bulb of energize or with torch all can, illuminator 1 outside, be provided with lampshade 2, so that make the light gathering.

During experiment, open illuminator 1, make the water surface of the light directive clear water 10 of illuminator 1, open water outlet flap 7 again, clear water 10 flows out from water delivering orifice 8, and light together penetrates with clear water 10, can see a luminous water column, and this tests, and to carry out effect in the darkroom more obvious.

Claims

1. simple and easy light total reflection experimental provision, comprise illuminator (1), water container (6), clear water (10), it is characterized in that on the inwall of water container (6), establishing blacking layer (11), at water container (6) end dress one deck fine sand (9), dress clear water (10) above the fine sand (9), on water container (6) wall of fine sand (9) layer top, set out the mouth of a river (8), locate to set out water cap (7) at water delivering orifice (8), establish water inlet pipe (5) in water container (6) wall top, water inlet pipe (5) is provided with valve (4), be provided with water container lid (3) on water container (6) top, illuminator (1) is equipped with at water container lid (3) center, the outer lampshade (2) that is provided with of illuminator (1).
