Abstract
The utility model discloses a reflecting rate tester which overcomes the defect that one layer of intermediate medium (slot wall glass) is needed when users measure an incident angle and a refraction angle with the original instrument, and thus, the application range is extended. The utility model is composed of an oblong transparent flume [1] with a marker at the bottom, and a vertical plane angle measuring device [2]. The utility model can be used for testing the refractivity of transparent liquid and transparent solid. Measuring accuracy can meet the requirement of a physical test in colleges and universities. If the angle measuring device is simplified and arranged on the flume wall, the utility model has the advantages of simple structure, low cost, easy self manufacture, small volume, etc. The utility model is suitable for a group test for the students in middle schools.
Description
The utility model belongs to the improvement of teaching and experiment equipment liquid refracting meter.
The liquid refracting meter that Chicago,U.S central authorities scientific instrument companies (CENTRALSCIENTIFICCO.CHICAGOU.S.A) arranged similar to the present invention.It is made of clear glass liquid bath and plane angle-measuring equipment.But when measuring incident angle i and refraction angle r, pass through one deck intermediate medium---cell wall glass with the refractometer that this protractor is horizontal.This just occurs is not directly to measure tested medium and the incident angle of air interface both sides and the drawback at refraction angle.
The purpose of this invention is to provide the incident angle of tested medium of a kind of direct measurement and air interface both sides and the device at refraction angle.
After the present invention changes angle-measuring equipment into setting, just avoided intermediate medium (cell wall glass), directly measured light and enter refraction angle and corresponding incident angle behind the tested medium, met refractive index n=sinr/sini condition fully by air.Also can be used for measuring the refractive index value of transparent solid.
Illustrated below in conjunction with accompanying drawing:
Fig. 1 is the front view of the novel detecting refractive index experiment instrument that designs of inventor.It is by the transparent liquid bath of rectangle ［ 1 ］, protractor ［ 2 ］ and aiming pivoted arm ［ 3 ］ three most formations.Liquid bath ［ 1 ］ can be fixed on the plate, lays or delineate underlined (point, line, thing) on its lower surface.Aiming pivoted arm ［ 3 ］ is installed on the protractor ［ 2 ］, protractor is fixed on two guide pillars ［ 4 ］, regulate screw handle ［ 5 ］, protractor ［ 2 ］ and aiming pivoted arm ［ 3 ］ can make 90 ° of sidelines of protractor and tested medium interface coplane along the upper and lower translation of guide pillar.Also be equipped with on the protractor one adjustable or proofreaied and correct, needle point and the 90 ° of sidelines location draw point ［ 6 ］ of surface levels altogether, judge tested medium interface location with it.The aiming pivoted arm can rotate around axle ［ 7 ］ (initial point).Separated by a distance on the pivoted arm have two parallel directrix pieces ［ 8 ］, and the center line of directrix piece is made the aiming datum line; The index line that pivoted arm center line double as takes measurement of an angle (three center line should on same plane), its angle value can be located to read in fenestella ［ 9 ］.
Fig. 2 is a kind of simple type structure of the present invention, is that angle-measuring equipment is fixed in cell wall, only is used to measure the refractive index value of transparency liquid.
The present invention has characteristics such as measuring principle is clear, rational in infrastructure, function expansion.Measuring accuracy meets the requirements (refractive index value of measuring water is 1.33 ± 0.01), is well suited for promoting the use of in the Physical Experiment of all kinds of big, special universities and colleges; The simple type structure is very simple especially, and volume is little, cost is low, be convenient to self-control, and measuring accuracy is unaffected, is well suited for each secondary school's Physical Experiment at present and uses.Replace the refractive index experiment of surveying the glass brick in the current teaching materials with extremely inaccurate " contact pin method " with it, it is very essential that middle school student are correctly set up physical concept.
Figure of description 1 is a front view of the present invention.
Figure of description 2 is a kind of simple type structural drawing of the present invention.
Claims (3)
1, a kind of detecting refractive index experiment instrument is partly to be made of the transparent liquid bath of rectangle [1], protractor [2] and aiming pivoted arm [3] three, it is characterized in that the angle-measuring equipment that will be made of protractor [2] and aiming pivoted arm [3] changes setting into.
2, detecting refractive index experiment instrument according to claim 1 is characterized in that this setting angle-measuring equipment can also can be fixed in the sidewall of transparent liquid bath ［ 1 ］ along two upper and lower translations of guide pillar.
