Abstract
The utility model discloses a light reflection demonstration instrument, which comprises a light source, a reflection mirror, and two flat plates A and B, wherein the reflection mirror is arranged in the middle of the flat plate A; the surface of the flat plate B is provided with an index plate; and the flat plate B is vertically arranged on the surface of the flat plate A via a fixing device. The light reflection demonstration instrument is simple in structure, convenient in operation and easy in carrying. When the light reflection demonstration instrument is used for demonstrating the light reflection principle, the light path of light reflection can be substantially visually demonstrated, thereby enabling students to fully understand the light reflection principle, and facilitating memory and application. The surfaces of the flat plate A and the flat plate B are white, color difference exists between illumination lights and the colors of the flat plate A and the flat plate B, so as to better demonstrate lights on the flat plate B.
Description
Technical field
The utility model relates to a kind of optical experiment instrument, is specifically related to a kind of demonstration instrument of light reflection, belongs to the technical field of teaching experimental equipment.
Background technology
According to the rectilinear propagation characteristic of light, light is mapped on the bright level crossing can produce reflection.Reflection ray, incident ray and normal are in same plane, and reflection ray and incident ray lay respectively at the both sides of normal, and they equate that with angle between the normal namely incident angle equals reflection angle.Normal is to be the 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 with light reflection mirror light to be reflected, make the light that comes from a direction be reflected to another direction, finally the luminous point of reflection often can be seen, and is in sight but light path generally is difficult for, and also has to utilize blank sheet of paper, level crossing, pin, protractor and electric torch combination light reflex principle to study, the more complicated but this method operates, stability is relatively poor.
The utility model content
The utility model is for a kind of simple in structure, easy to operate, better, portable demonstration instrument of light reflection of demonstration effect of above-mentioned not enough design, and purpose is: make the student can understand fully light reflection principle in doing experimentation, be convenient to memory and utilization.
Technical solution of the present utility model:
A kind of demonstration instrument of light reflection, comprise light source, catoptron, it is characterized in that: described demonstration instrument of light reflection also comprises two dull and stereotyped A and B, and described catoptron is installed in the position in the middle of the dull and stereotyped A, dull and stereotyped B surface is provided with index plate, and dull and stereotyped B is vertically mounted on the surface of dull and stereotyped A by stationary installation.
From the index plate centre position on dull and stereotyped B surface dull and stereotyped B being divided equally is two dull and stereotyped E and F, is connected through the hinge between dull and stereotyped E and the F.
Described dull and stereotyped E bottom is provided with two projections, and two grooves that arrange with dull and stereotyped A surface match.
Described dull and stereotyped E one side is connected by gim peg with dull and stereotyped A.
The irradiation light that described light source is launched is banded light.
There is aberration in the color of described irradiation light and dull and stereotyped A and B.
As preferably, described irradiation light is red light belt, and described dull and stereotyped A and B surface are white.
The beneficial effects of the utility model:
The utility model is simple in structure, easy to operate, be easy to carry, demonstrate by come the light reflex principle with the utility model, can demonstrate very intuitively the light path of bright dipping reflection, make the student understand fully light reflection principle, be convenient to memory and utilization.The dull and stereotyped A of the utility model and dull and stereotyped B surface are white, and there is aberration in the color of irradiation light and dull and stereotyped A and dull and stereotyped B, and purpose is in order to make things convenient for light can better show on dull and stereotyped B.

Embodiment
As shown in Figures 1 to 4, a kind of demonstration instrument of light reflection, comprise light source 1, catoptron 2, described demonstration instrument of light reflection also comprises dull and stereotyped A4 and dull and stereotyped B3, described catoptron 2 is installed in the position in the middle of the dull and stereotyped A4, dull and stereotyped B3 surface is provided with index plate 5, dull and stereotyped B3 is vertically mounted on the surface of dull and stereotyped A4 by stationary installation, from index plate 5 centre positions on dull and stereotyped B3 surface dull and stereotyped B3 is divided equally and to be dull and stereotyped E8 and dull and stereotyped F14, connect by hinge 9 between dull and stereotyped E8 and the dull and stereotyped F14, dull and stereotyped E8 bottom is provided with two projections 6, and two grooves 7 that arrange with dull and stereotyped A4 surface match, dull and stereotyped E8 one side is connected by gim peg 10 with dull and stereotyped A4, the irradiation light that light source 1 is launched is banded light, and there is aberration in the color of irradiation light and dull and stereotyped A4 and dull and stereotyped B3, as preferably, described irradiation light is red light belt, and described dull and stereotyped A4 and dull and stereotyped B3 surface are white.
Use procedure:
Dull and stereotyped A4 level is put on the table, dull and stereotyped B3 is vertically mounted on the surface of dull and stereotyped A4 by stationary installation, make dull and stereotyped E8 bottom be provided with two projections 6 and be positioned at two grooves 7 that dull and stereotyped A4 surface arranges, afterwards dull and stereotyped E8 one side is connected by gim peg 10 with dull and stereotyped A4, then tests according to light reflection principle.
Experimental procedure one
According to shown in Figure 5, make dull and stereotyped E8 and dull and stereotyped F14 be positioned at same plane, the redness that the student sends light source 1 is shone light along dull and stereotyped B3 toward mirror 2, this moment, students' union found that reflection ray 11, incident ray 12 and normal 13 are in same plane, when changing incident ray 12 direction, reflection ray 11 changes with the change of incident ray 12, and reflection ray 11 and incident ray 12 lay respectively at the both sides of normal 13, they equate that with angle between the normal 13 namely incident angle equals reflection angle.
Experimental procedure two
We can obtain the reflection of light law according to above-mentioned experiment, reflection ray 11, incident ray 12 and normal 13 in same plane, the both sides of reflection ray 11 and incident ray 12 separation normals 13, reflection angle equals incident angle.
