Abstract
The utility model belongs to teaching instruments, and in particular relates to a refraction phenomenon demonstrator. The demonstrator comprises a first frame body (1), a second frame body (3) and a third frame body (6) which are sequentially superposed from bottom to top; each of the first frame body (1) and the third frame body (6) is provided with a water injection port (2); the second frame body (3) is provided with a through hole (4); a glass block (5) penetrates through the through hole (4) and is inserted into the second frame body (3); a laser source (7) is arranged on the upper bottom surface of the third frame body (6); a reflector (8) is also arranged on the upper bottom surface of the third frame body (6); the reflector (8) is movably connected with the upper bottom surface of the third frame body (6); and supporting legs (9) are arranged at the lower bottom surface of the first frame body (1). The demonstrator has the advantages of simple structure, convenience and practicability, and can assist students in linking theory with practice and intuitively understanding the refraction phenomenon of light.
Description
Technical field
The utility model belongs to instruments used for education, particularly a kind of refraction effect demonstrator.
Background technology
When light was gone into another kind of transparent medium from a kind of transparent medium oblique fire, the direction of propagation generally can change, and this phenomenon is the refraction of light.The teacher often adopts the mode of preach when lecturing this knowledge point, the student can only the spoon-feed passive acceptance in ground, and theory does not contact reality, and teaching efficiency is relatively poor, knows the theoretical main cause that can not be applied to practical experience of life though this also is a Most students.There is not the refraction effect apparatus for demonstrating in the prior art.
The utility model content
The purpose of the utility model provides a kind of refraction effect demonstrator, and this demonstrator can help the student to explore the refraction effect of light intuitively.
The scheme that the utility model solve the technical problem is: a kind of refraction effect demonstrator; It comprises first framework, second framework and the 3rd framework that stacks gradually from lower to upper; On first framework and the 3rd framework water filling port is set; On second framework through hole is set, glass blocks passes through hole and is inserted in second framework, and the upper bottom surface of the 3rd framework is provided with LASER Light Source.
During demonstration, in first framework and the 3rd framework, inject different liquid earlier, open LASER Light Source, can observe the refraction effect of light in first framework, second framework and the 3rd framework.Extract the glass blocks in second framework, can observe another propagation broken line of light.Change the class of liquids in first framework and the 3rd framework, can observe new propagation broken line again.
As further technical scheme, the upper bottom surface of said the 3rd framework is provided with reflective mirror, and the upper bottom surface of reflective mirror and the 3rd framework flexibly connects.
Reflective mirror is set, the direction and the angle of convenient adjustment light source.
As further technical scheme, the bottom surface of said first framework is provided with leg.
Bottom surface is provided with leg, can light be appeared the 3rd framework.
In sum, the utlity model has simple in structure, convenient and practical advantage, can help the student to combine theory and practice together, understand the refraction effect of light intuitively.
