Abstract

The utility model discloses a light reflection and refraction demonstrator, which is a square casing. The front face of the casing is made from transparent materials, and the other faces evenly made from non-transparent materials and the inner surfaces are smeared with black lacquers. A movable handle is arranged on the middle lower portion of the back face of the casing and is connected with a 'Z'-shaped frame in the casing. A laser light is arranged on the upper end of the 'Z'-shaped frame, a plane mirror is installed on the position near the median part of the bottom in casing, and light which is radiated by the laser light is rightly radiated on the plane mirror. Due to the adoption of the structure, the laser light sending out red light beam is used as light source, and the penetrating ability of the light beam is strong, and the strong light beam is formed without passing through narrow slits. The incidence light and reflection light and the refraction light are clearly demonstrated, which improves the visibility of demonstrated experiment.

Description

Reflection of light and refraction demonstration device

The utility model relates to a kind of instrument of demonstrating the refraction reflectivity properties of light.

At present, in the junior physics Experiments of Optics, about reflection of light and these two lecture experiments of refraction, usually will be with instruments such as optical disk and annexes, its light source is made up of incandescent lamp bulb and lens, produces Ray Of Light through a slit, because of the more weak need of light carry out in the darkroom.Use it to do these two whens experiment, during not only instrument adjustment trouble, and experiment shown incident ray, reflection ray and refracted ray a little less than, visibility is low, experiment effect is poor.

The purpose of this utility model is exactly that design at the problem of instrument adjustment trouble, demonstration weak effect in the present Experiments of Optics a kind of do not need that the light path carrying out in the darkroom, show clearly becomes clear, the demonstration device of good demonstration effect.

The purpose of this utility model is to realize like this, this demonstration device is a square box, described casing front is that transparent material is made, each side of other of case is opaque material, and inside surface all scribbles pitch-dark, in middle and lower part, casing back one flexible handle is arranged, " Z " shape support in this flexible handle and the casing, in " Z " shape support upper end one laser lamp is housed, the case inner bottom surface hits exactly level crossing of forward installation, the light that laser lamp sends is just in time penetrated on level crossing, and a switch and two binding posts are arranged in the side of casing, and casing back one side has a movable wicket.

Owing to adopt said structure, used the laser lamp as light source of emission red beam, the penetration capacity of light beam needs by force and not can form very strong light beam by slit, and the incident ray of demonstration, reflection ray and refracted ray are clear bright, has improved the visibility of lecture experiment.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing

Among the figure: 1, square box 2, transparent front panel 3, " Z " shape support 4, laser lamp 5, level crossing 6, switch 7, binding post 8, flexible handle 9, movable wicket

In Fig. 1: show " Z " shape support (3) in the square box (1) of demonstration device and transparent front panel (2), the square box (1) and laser lamp (4) mounted thereto, square box (1) inner bottom surface hits exactly the forward level crossing (5) that has, and a side is provided with switch (6) and binding post (7).

In Fig. 2: show flexible handle (8) and movable wicket (9) that the back side of square box (1) connects with " Z " shape support (3) in the case.

In Fig. 3: show " Z " shape support (3) and connect flexible handle (8), laser lamp (4) on it.

In Fig. 4: show the switch (6) in the circuit diagram.

In Fig. 5: show laser lamp and go up the reflection ray that forms at level crossing (5).
