Abstract

The utility model discloses an optical experiment demonstrating device. The optical experiment demonstrating device comprises a pedestal, a water tank arranged on the pedestal, a support and a fixing clamp arranged on the support, the support is fixed on the pedestal and positioned on the outer side of the water tank, and the fixing clamp is used for fixing a light source or a lens; and a rotating base plate is arranged below the pedestal so that the pedestal can realize rotatable demonstration. According to the optical experiment demonstrating device, an optical demonstrating experiment can be demonstrated in a bright classroom, and special requirements for teaching conditions in a school are avoided.

Description

A kind of Experiments of Optics apparatus for demonstrating

Technical field

The utility model relates to a kind of demenstration method and device, especially a kind of Experiments of Optics apparatus for demonstrating.

Background technology

In physics teaching in secondary school, the awkward demonstration of Experiments of Optics, wherein with " direct reflection of light, diffuse reflection ", " convex lens are to the effect of converging of light " and " concavees lens are to the disperse function of light " are the most outstanding.In practice; The teaching demonstration of these experiments needs the darkroom to realize; And domestic most middle school does not have the darkroom; This gives, and the experiment about opticator brings inconvenience in the physics teaching, and the therefore a kind of demenstration method or device that can reduce the environment bright influence becomes the technical barrier that presses for solution.The 7th the national middle school physics young teacher who holds in Liaoning in October, 2006 imparts knowledge to students in the contest; To direct reflection, the diffuse effect of light best be level middle school teacher's Yan Xiaoling of Hui Zhou curry favour Yanggao County, Guangdong the method for demonstration; This method has broken through the restriction of environment bright with the mode of enhancing contrast; But also let simultaneously the implacable condition of some schools: 1. blackboard must be an irony, otherwise magnet can't be inhaled on blackboard; 2. blackboard must be definitely smooth, otherwise light path can be intermittent.Yet the blackboard of a lot of schools is aluminium matter or other material, and the blackboard of using of a specified duration unavoidably can be uneven.

The utility model content

For solving the problems of the technologies described above, the utility model provides a kind of Experiments of Optics apparatus for demonstrating, and this device can make optical demonstration experiment in bright classroom, demonstrate, and the school instruction condition is not had special demands.

The described a kind of Experiments of Optics apparatus for demonstrating of the utility model; Comprise base, be positioned over water vat, the support on the base and be arranged at the geometrical clamp on the support, said support is fixed on the base, is positioned at the water vat outside; Said geometrical clamp can up-down adjustment, is used for fixing light source or lens.

As the further improvement of the utility model, the base below is provided with swivel base, makes the rotatable demonstration of base.

Compared with prior art; The technique effect of the utility model is: because clear water is weaker than air to scattering of light; So being employed in, the utility model carries out the Experiments of Optics demonstration in the water vat; Supply the light of observation more limpid in sight when making experiment to a great extent, can finely weaken the negative effect that bright photoenvironment brings the Experiments of Optics demonstration; The utility model is made simple, with low cost, easy to operate, can well solve the problem of site condition restriction, and the demonstration effect has very strong stereoscopic sensation.

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the vertical view of Fig. 1;

Among the figure: 1-base, 2-support, 3-geometrical clamp, 4-water vat, 5-swivel base.

Embodiment

Further describe the technical scheme of the utility model below, but require the scope of protection to be not limited to said.

Extremely shown in Figure 2 like Fig. 1; A kind of Experiments of Optics apparatus for demonstrating that the utility model provides; Draw together base 1, be positioned over water vat 4, the support 2 on the base 1 and be arranged at the geometrical clamp 3 on the support, said support 2 is fixed on the base 1, is positioned at water vat 4 outsides; Said geometrical clamp 3 can up-down adjustment, is used for fixing light source or lens; Said support 2 is telescopic; Said base 1 below is provided with swivel base 5, makes the rotatable demonstration of base.

The concrete experimental technique of the described a kind of Experiments of Optics apparatus for demonstrating of the utility model is following.

Embodiment 1

Light is tested along rectilinear propagation in water

An amount of clear water of in glass jar, packing into; In water, add a little yellow chalk powder, the red laser torch is fixed on the support with geometrical clamp, open and inject in the glass jar; In direction, promptly can be observed the light path in water of light clearly along rectilinear propagation against light beam.

Embodiment 2

Direct reflection and diffuse reflection experiment

Two red laser torch are fixed on the support with geometrical clamp respectively, and are in juxtaposition, process two bundle parallel light sources.An amount of clear water of in the glass water vat, packing into; In water, add a little yellow chalk powder; And put into a level crossing, two red laser torch are opened, on the level crossing of oblique fire in the glass water vat; On direction, promptly can be observed parallel optical path of incident light and parallel reflected light light path against light beam.Embed broken mirror sheet on rough plasticine surface, make broken mirror sheet on different plane.Take out level crossing, the plasticine that is embedded with broken mirror sheet is put into glass jar, the directional light oblique fire on the broken mirror sheet of plasticine, on the direction against light beam, promptly can be observed parallel clearly optical path of incident light and uneven reflected light light path.

Embodiment 3

Convex lens are tested the disperse function of light the converging action and the concavees lens of light

Two red laser torch are fixed on the support with geometrical clamp respectively, and are in juxtaposition, process two bundle parallel light sources.An amount of clear water of in the glass water vat, packing into; In water, add a little yellow chalk powder, between red laser torch and glass jar, place convex lens, parallel rays is seen through convex lens inject in the water; On direction, promptly can be observed and assemble light path clearly against light beam.Take out convex lens, between red laser torch and glass jar, place concavees lens, parallel rays is seen through concavees lens inject in the water, on direction, promptly can be observed and disperse light path clearly against light beam.

Embodiment 4

Light is the experiment of the refraction effect in the oblique fire entry from air

The red laser torch is fixed on the support with geometrical clamp, optical disk is placed in the water vat, an amount of clear water of in water vat, packing into adds a little yellow chalk powder in water, makes water level just in the central authorities of optical disk.The red laser torch is opened, made red laser from air, in the oblique fire entry, promptly can be observed airborne light path and the light path that takes place in the water of refraction back in the front with certain angle.
