The purpose of this utility model and solve its technical problem underlying and realize by the following technical solutions: a kind of multifunctional optical demonstration box, comprise glass atomization case, above glass atomization case, removable glass plate and fastening glass panels are set, horizontal positioned two laser pens above removable glass plate, laser pen opposite vertically arranges fan A, is horizontally disposed with fan B under fan A, is level crossing under fan B, beaker is placed, the built-in ultrasonic ultrasonic delay line memory of beaker bottom glass atomization case; Concavees lens and convex lens are established in laser pen bottom.
The power supply and blower A of described ultrasonic ultrasonic delay line memory, the power supply of fan B are located at the rear portion of glass atomization case.
During use, add water in glass atomization case, by optical elements such as laser torch, glass, level crossing, lens, observe reflection and the refraction effect of light, observe these optical elements dispersing and converging action light simultaneously.
The utility model compared with prior art has obvious advantage and beneficial effect.From above technical scheme, the utility model has following characteristics:
1. test the making that innovative point is exactly multifunctional box, the experiments such as light is linearly propagated, the reflection of light, the refraction of light can be demonstrated simultaneously.It makes the Experiments of Optics on classroom become vividly, intuitively, bring visual experience intuitively to student, make student more easily accept knowledge, the process of experiment also meets the characteristics of cognition of student more.
2. present light path comparatively speaking with the mode of tradition dust, smog, it is more stable, more directly perceived, vivider that this device adopts the method for ultrasonic water smoke to present light path phenomenon, more clean environment firendly, can not damage student's health.
3. this apparatus structure is simple, easy to operate, and phenomenon is obvious, and cost is low simultaneously, can multi-angle observation to experimental phenomena, be well suited for the teaching request of most schools.

During use, in glass atomization case 12, add water 9, by optical elements such as laser torch, glass, level crossing, lens, observe reflection and the refraction effect of light, observe these optical elements dispersing and converging action light simultaneously.
A kind of multifunctional optical demonstration box, comprise glass atomization case 12, glass atomization case 12 arranges removable glass plate 2 and fastening glass panels 3 above, removable glass plate 2 is horizontal positioned two laser pens 1 above, laser pen 1 opposite vertically arranges fan A4, is horizontally disposed with fan B5 under fan A4, is level crossing 6 under fan B5, beaker 8 is placed, the built-in ultrasonic ultrasonic delay line memory 7 of beaker 8 bottom glass atomization case 12; Concavees lens 11 and convex lens 10 are established in laser pen 1 bottom.
During use, in glass atomization case 12, add water 9, by optical elements such as laser torch, glass, level crossing, lens, observe reflection and the refraction effect of light, observe these optical elements dispersing and converging action light simultaneously.
Specific experiment operation can divide following steps:
1. the rectilinear propagation of light
(1) allow light inject multifunctional box, can obviously see that bright dipping is linearly propagated in atmosphere.
(2) allow light inject drip when having in the water of milk, can obviously see that bright dipping is linearly propagated in a liquid.
2. the reflection of light
The reflection law of light can be summed up: 1. can demonstrate reflection ray and incident ray separation normal both sides with laser irradiated plane mirror; 2. allow incident angle equal 60 °, 45 °, 0 °, observe the size of reflection angle, reach a conclusion: reflection angle equals incident angle; 3. demonstrate light path reversible, make light incident along the direction of reflection ray, can find out that reflection ray penetrates along the direction of original incident ray.
3. the refraction of light
(1) when light slants in water, the direction of propagation there occurs change.When light vertical fluid level is incident, the direction of propagation is constant.
(2), when injecting convex lens with the parallel rays of two laser pens, convex lens have converging action to light.The point assembled is the focus of convex lens.
(3) when directional light injects concavees lens, light is refracted, and concavees lens have disperse function to light.
4. demonstrate the color of object
The color of transparent substance is determined by the coloured light by it, also can show with this instrument, as long as inject the liquid of different colours in container, just can see different experimental phenomenas.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, anyly do not depart from technical solutions of the utility model content, the any simple modification done above embodiment according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
