Abstract
The utility model relates to a teaching tool for demonstrating optics fundamental, which belongs to the category of stationery tools. The utility model comprises a support frame and a demonstration table, wherein the interior of the support frame is provided with a bottom board, a support rod is erected on the bottom board and the upper part of the support rod is provided with a laser torch. The middle of the demonstration table is provided with a rectangular bottom board Q, and a partition board E is erected on the middle of the rectangular bottom board Q. The partition board E is connected with a partition board F through a hinge on one side of the middle of the rectangular bottom board Q. A round hole is arranged on the middle position of the rectangular bottom board Q where the partition board E and the partition board F are crossed. Two steel wires are penetrated in the round hole. The steel wires are connected with memory pointers in the front sides of the partition board E and the partition board F. The surfaces of the boards are carved semi-round scale lines near the pointers. The steel wires are connected with steering handles on the back sides of the partition board E and the partition board F. The rectangular bottom board Q is also provided with a plane mirror under the pointers. The utility model can demonstrate the reflection law in the optics in transmutability. The utility model not only is convenient for teachers to teach, but also is convenient for students to learn. The utility model is very helpful for building the students' problem parsing and problem solving abilities.
Description
Technical field
The utility model relates to a kind of teaching aid, particularly relates to a kind of teaching aid of demonstrating optical principle, is to the replenishing of existing middle school teaching apparatus kind, and belongs to the school supply and stationery category, and suitable middle school student and teacher use in teaching.
Background technology
At present, the used teaching aid of people is a lot, but function singlenesses all just designs at the content that needs separately to show.Optics is important and one of the content of beyonding one's depth in the physics course in middle school, and student and teacher press for teaching aid targetedly, yet but are difficult to find this class teaching aid on market.For example, the teacher is when explanation reflection of light law, always adopt the mode of putting picture recording to impart knowledge to students, though it is relatively more directly perceived, but lack the chance that the student starts to test, the enthusiasm that can not mobilizing students initiatively participates in is helpless to cultivate students ' analysis problem and problem-solving ability, thereby bring certain difficulty to teaching, even have influence on student performance and learning interest.
The utility model content
The purpose of this utility model is to overcome the prior art above shortcomings, improve by research, provide a kind of teaching aid of demonstrating optical principle,, this novel teaching aid is simple in structure, workable, can change the reflection law that shows optics, both be convenient to the teacher and finished teaching task quickly, improved the interest and the manipulative ability of student's study again, very helpful to cultivating students ' analysis problem and problem-solving ability.
The technical scheme that the utility model provides is: the teaching aid of this demonstration optical principle, include framework, and be characterized in that described framework is made of a support and a Demonstration table, wherein
One base plate is arranged in the described support, erect a support bar on the base plate, be provided with to the upper angled of support bar a laser flashlight;
One rectangular base plate Q is arranged in the described Demonstration table, erect in the middle of the rectangular base plate Q dividing plate E is arranged, dividing plate E docks with dividing plate F by the hinge that is positioned on the middle side of rectangular base plate Q, the hinge that dividing plate F can dock rotates for axle, meet at rectangular base plate Q position in the middle at dividing plate E and dividing plate F and be provided with circular hole, be installed with two steel wires in the circular hole, this steel wire is at the memory pointer that is positively connected with of dividing plate E and dividing plate F, on near the plate face memory pointer, be carved with the scale mark of half garden shape, this steel wire is connected with handle at the back side of dividing plate E and dividing plate F, also is provided with a level crossing on the rectangular base plate Q below the memory pointer.
The material of this teaching aid is not limited to plank in such scheme, also should comprise plastics, metal and other material, for example with the cardboard that certain intensity is arranged.
Design concept of the present utility model is: the angle of adjusting laser flashlight on the support, make incident light A incide the central point O of level crossing along dividing plate E plane, on dividing plate F plane reflection ray BO appears then, reflected light BO disappears when rotating dividing plate F, illustrate that reflection ray follows incident ray and normal at grade; Dividing plate F is transferred back to original position again, seen reflection ray again, at this moment carefully stir pointer, write down the position of incident ray and reflection ray, close laser flashlight, measure incident angle and reflection angle, and draw the conclusion that incident angle equals reflection angle with regard to the available quantity hornwork.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, workable, can change the reflection law that shows optics, both be convenient to the teacher and finished teaching task quickly, improved the interest and the manipulative ability of student's study again, very helpful to cultivating students ' analysis problem and problem-solving ability.
