Abstract
The utility model discloses an optical comprehensive demonstration device comprising a triangular prism which is formed by the fixed connection and enclosure of a bottom surface, a top surface and three rectangular faces. An inner surface of the bottom surface is a plane mirror. The top surface and the three rectangular faces are made of glass, and the top surface is provided with a small hole. The bottom surface, the top surface and the three rectangular faces are fixed through a bonding mode. The optical comprehensive demonstration device has the advantages: (1) the device is formed by the bottom surface, the top surface and three rectangular faces, and the structure is simple; (2) a plurality of optical principles of rectilinear propagation of light, reflection of light, refraction of light, dispersion of light and the like can be demonstrated, and the device has various functions.
Description
Technical field
The utility model relates to a kind of junior middle school physics teaching apparatus, particularly a kind of Optical Synthetic demonstration device.
Background technology
At present, in the process of giving lessons of junior physics, need respectively to lecture rectilinear propagation, reflection of light, the refraction of light and several parts such as dispersion of light of light, when talking about each part, need to demonstrate with different demonstration devices, thus very inconvenient.
Summary of the invention
Problem to be solved in the utility model is: a kind of simple in structure, the Optical Synthetic demonstration device that can demonstrate multiple optical principle is provided.
In order to solve the problems of the technologies described above, Optical Synthetic demonstration device of the present utility model, comprise by bottom surface, end face and three rectangular surfaces and being fixedly connected with and the triangular prism that surrounds, the inside surface of described bottom surface is a level crossing, described end face and three rectangular surfaces are made by glass, and described end face is provided with an aperture.
Optical Synthetic demonstration device of the present utility model, described bottom surface, end face and three rectangular surfaces are fixed by the mode of bonding.
The beneficial effect that the utility model is obtained is: (1) is comprised of bottom surface, end face and three rectangular surfaces, thereby simple in structure; (2) can demonstrate rectilinear propagation, reflection of light, the refraction of light and a plurality of optical principles such as dispersion of light of light, thereby diverse in function.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, bottom surface, 2, rectangular surfaces, 3, end face, 4, aperture.
Embodiment
As shown in Figure 1, Optical Synthetic demonstration device of the present utility model, comprise by bottom surface 1, end face 3 and three rectangular surfaces 2 and being fixedly connected with and the triangular prism that surrounds, the inside surface of described bottom surface 1 is a level crossing, described end face 3 and three rectangular surfaces 2 are made by glass, and described end face 3 is provided with an aperture 4; Described bottom surface 1, end face 3 and three rectangular surfaces 2 are fixed by the mode of bonding.
The demonstration of the rectilinear propagation principle of light: the teacher can pass into some smog from the aperture 4 of demonstration device top, then injects Ray Of Light with laser lamp from aperture 4, can observe light from the demonstration device side along the track of rectilinear propagation.
Embodiment 2
The demonstration of reflection of light principle: the aperture 4 above demonstration device passes into some smog, then with laser lamp from aperture 4 inject Ray Of Light be mapped to the bottom level crossing reflect, can observe from the demonstration device side propagation track of incident ray and reflection ray.
The demonstration of the refraction principle of light: from the aperture 4 a part of water of injection of demonstration device top, pass into again some smog, then be slanted through Ray Of Light to the water surface with laser lamp from aperture 4, the refraction effect of light will occur in light from air oblique fire entry, can observe from the demonstration device side propagation track of incident ray and refracted ray.
The demonstration of the chromatic dispersion principle of light: demonstration device is lain against on surface level, allow solar irradiation be mapped on a rectangular surfaces 2 of demonstration device, because seeing through glass from air, light enters demonstration device, be mapped to air from the inner glass that sees through of demonstration device again, repeatedly refraction has occured, so the dispersion phenomenon of light has just occured.If injected water operates in demonstration device, phenomenon can be more obvious.
Therefore, Optical Synthetic demonstration device of the present utility model is to merge in the junior physics textbook optical demonstration experiment in a comprehensive demonstrator of one.This demonstration device can be demonstrated light along the refraction of rectilinear propagation, reflection of light, light, a plurality of Experiments of Optics such as dispersion of light.
