Description
Technical field
The utility model relates to a kind of reflection of light experiment teaching aid.
Background technology
In middle and primary schools teaching, in the test of research reflection of light law, generally need experimenter oneself draw under index path, penetrated and left light path vestige and cannot realize light.Like this experiment since just more loaded down with trivial details, be unfavorable for probing into simply experimental phenomena and, use merely infrared ray ray plank, experiment seem uninteresting stiff.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of reflection of light experiment teaching aid, what the design of this device can be attended class as high school teachers draws appearance within the class period, before can be at school, first knowledge be showed to student with lively teaching aid, excite student's interest, improve the quality of attending class.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of reflection of light experiment teaching aid, comprise that the Lights section and light path manifest part, described the Lights section comprises finger star pen and support, described finger star pen is fixed on support, described light path manifests part and comprises fluorescence cloth, base for supporting, rule and level crossing, described fluorescence cloth is fixed on base for supporting, described rule is arranged on three sides of fluorescence cloth, described level crossing is arranged on base for supporting, and level crossing is positioned at the dead ahead of fluorescence cloth, and in the centre position of fluorescence cloth, described finger star pen is relative with level crossing; From leg-of-mutton congruence property, by reading the calibration points of light path vestige on fluorescence cloth, the i.e. relation of provable incident ray and reflection ray.By observing, to inject the other way around the light path that light obtains overlapping, can draw the reversibility of light path.Can the half of fluorescence cloth, along axis deflection certain angle, be observed after injecting light and be shown reflection ray at second half, and then analyze incident ray and the whether coplanar problem of reflection ray.
As preferred technical scheme, described support comprises base, and is welded on the pole of base top, and be set on pole, and the sliding part that can slide along pole, sliding part one side is provided with lock screw, and opposite side is provided with set collar, described lock screw one end spiral is to sliding part inside, and offset with pole, the other end is provided with force section, and described set collar is connected with a threaded rod, and be threaded with sliding part by this threaded rod, described base and base for supporting offset.
As preferred technical scheme, described set collar has a fixing bellmouth that refers to star pen use, and described finger star pen is taper, and it has the tapering identical with bellmouth.
As preferred technical scheme, the surfacing of described fluorescence cloth.
As preferred technical scheme, described level crossing has a smooth minute surface.
The beneficial effects of the utility model are: this device intuitively vivo shows reflection of light law related content in secondary curriculum very much.The angle of injecting that refers to star pen by continuous change, the vestige on fluorescence cloth is recording the relation of each incident ray and reflection ray.On fluorescence cloth, leave this experiment of light path vestige and manifest noveler, can give student's the classroom enjoyment of taking, student does not need time-consuming described point simultaneously, can obtain the reflection law of light by observing scale on fluorescence cloth.Facilitate teacher to explain, be also beneficial to observation of students exploring law.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
