Abstract
A light reflex demonstration instrument relates to an optical testing instrument, in particular to a light reflex demonstration instrument, which comprises a light source, a reflecting mirror, a bracket, a base plate 1 and a hollow transparent semicircular container 2 arranged on the base plate 1. Wherein, the reflecting mirror 3 is arranged at a center of a diameter line 21 of the transparent container 2. A semicircular bracket 4 sharing the same circle center of the transparent container 2 and with a radius larger than that of the transparent container is arranged out of a circumference of the semicircular bracket. A focus light source 5 that can move circularly along the semicircular bracket is positioned on the semicircular bracket and towards the reflecting mirror 3. The transparent container is filled with liquid. Suspended particles are added into the liquid. A sliding chute 41 along an arch and on one side of the focus light source of the semicircular bracket. The focus light source is positioned in the sliding chute to realize free slide. The utility model can visually demonstrate light reflex path, thus providing students with a visual light path concept and improving teaching effect and quality.
Description
One, technical field
The utility model is a kind of instrument of Experiments of Optics, and the demonstration instrument of light reflection especially belongs to the technical field of teaching experimental equipment.
Two, background technology
The rectilinear propagation character of light, light are mapped to the level crossing of light, and perhaps the interface of two media as the interface of water and air, can produce reflection.Reflection ray, incident ray and normal at grade, the separation of reflection ray and incident ray is in the both sides of normal, their angles between normal equate that promptly incident angle equals reflection angle.Normal is to be the research optical problem, has added the incidence point by light when drawing light path, and perpendicular to the straight line of minute surface.In the teaching of optics, experiment to the reflection of light aspect, generally all be light to be reflected with light reflection mirror, the light that comes from a direction is reflected on another direction, and the luminous point of final reflection can be seen often, because light path generally is difficult in sight, therefore, when demonstrating the reflection of light feature to the student, directly perceived inadequately, the effect of influence demonstration.
Three, summary of the invention
1, technical matters
Goal of the invention of the present utility model just provides a kind of demonstration instrument of light reflection of simple, directly perceived, good demonstration effect.
2, technical scheme
Demonstration instrument of light reflection of the present utility model, comprise light source, catoptron, support, it is characterized in that on base plate, being provided with a hollow half-terete transparent vessel, central authorities are provided with catoptron on the diameter limit of transparent vessel, on the base plate, outside the circumference of transparent vessel, be provided with one and transparent vessel concentric, radius is greater than the semi-circular bracket of transparent vessel, on semi-circular bracket, be provided with a condensation light source that can move along the circular edges of semi-circular bracket, this condensation light source is aimed at catoptron, full of liquid in transparent vessel adds the particulate that can float on a liquid in liquid.Be provided with a side of condensation light source on semi-circular bracket, be provided with a chute along circular arc, condensation light source is arranged in this chute, can be free to slide.
This experiment is to fill water in semicircle organic glass container, a catoptron is arranged in the bottom, from circular arc, inject at an angle the water to the reflective mirror of bottom surface with beam of laser, light beam will reflect incident light and the reflected light both sides at normal at an angle, and equate Here it is reflection of light law with the angle of normal.
3, beneficial effect
The utility model can be demonstrated the light path of bright dipping reflection very intuitively, thereby gives one of student light path notion intuitively, improves teaching effect and quality.
Four, description of drawings
Fig. 1 is a general structure synoptic diagram of the present utility model, and base plate 1, transparent vessel 2, diameter limit 21, catoptron 3, semi-circular bracket 4, condensation light source 5 are wherein arranged.
Fig. 2 is the vertical view of Fig. 1.Chute 41 is wherein arranged.
Five, specific embodiments
Structure of the present utility model comprises light source, catoptron, support, on base plate 1, be provided with a hollow half-terete transparent vessel 2,21 central authorities are provided with catoptron 3 on the diameter limit of transparent vessel 2, on the base plate 1, outside the circumference of transparent vessel 2, be provided with one and transparent vessel 2 concentrics, radius is greater than the semi-circular bracket 4 of transparent vessel 2, on semi-circular bracket 4, be provided with a condensation light source 5 that can move along the circular edges of semi-circular bracket 4, this condensation light source 5 is aimed at catoptron 3, full of liquid in transparent vessel 2 adds the particulate that can float on a liquid in liquid.Be provided with a side of condensation light source 5 on semi-circular bracket 4, be provided with a chute 41 along circular arc, condensation light source 5 is arranged in this chute 41, can be free to slide.
Light be can't see light beam through pure empty G﹠W, have only dust, smog are arranged in the air, there is particulate just can see light beam in the water, so in semicircle organic glass container, will add some milk particulates, or rosin particulate, produce scattering phenomenon during these particulates of light beam process, just can see light beam.Class demonstration just can be seen the light of incident and the light of reflection, and the process of light path can both have been seen clearly.
